Talk:Periodic table (extended)

Incorrect Electron Configuration
This extended periodic table is not correct. Lanthanum, for example, has one d electron, and zero f electrons, and lutetium has 14 f electrons. The correct extended periodic table has the f elements inserted after one family (vertical column) of the d elements, that is, the d block is split by the f elements, and similarly the g block inserts one family into the f elements, again splitting the f elements. The first element with a g orbital in its ground state is unbitrium, element 123. This table is way off. -Steiner
 * I think you'll find most theorists would disagree. Electron configurations are not static: electrons skip around through the levels all the time - at any instant, a sample of an element will present a "boltzmann distribution" of populated configurations. (What you are thinking of are ground state configurations for isolated gas phase atoms: I don't believe we find much monatomic gaseous lutecium in everyday life, do you? ;-) Moreover, the "orbital approximation", where we regard each electron as a discrete entity with its own personalized set of quantum numbers, is just that: an approximation. It is a good one for light elements, but increasingly breaks down as nuclear charge Z increases, with increased spin-orbit coupling. By the f-block (and particularly the actinides), spin-orbit coupling is the dominant factor. The very concept of a "g-block" is moot, as no-one has yet synthesized these elements, and their electron configurations can at present only be guessed at - but we would strongly suspect the orbital approximation would be in tatters by that stage.--feline1 10:55, 11 January 2007 (UTC)


 * I disagree, and I think I'm not alone. In the current configuration, the claim is that lanthanum has an f electron in its ground state and no d electron, when in fact the electron configuration of lanthanum has one d electron, and no f electrons.  This is not speculation.  Additionally, based on the current table's assumptions, ytterbium and nobelium have 14 f electrons, which they do not--they have 13.  Furthermore if the concept of a "g-block" is a moot point, then why is it included in this periodic table?  I encourage you to look up the work of Darleane Hoffman at Lawrence Berkeley. -Steiner —The preceding unsigned comment was added by 128.165.118.5 (talk) 23:02, 11 January 2007 (UTC).


 * To follow your point here is an image of how it should look.
 * [[Image:Periodic_table_Proposed_redesign.JPG]]
 * This is the accurate representation of this as you will see in most short periodic tables Lanthanum and Actinium are shown in the same group as Scandium and Yttrium and 14 elements across f block ends with Lutetium, for lanthanides, and Lawrencium, for actinides, not Ytterbium and Nobelium as show on this page. I'll check and site my sources so that an official edit can be made to this effect.   -->Bensrob 03:16, 8 November 2007 (UTC)

Colour
What colour should I colour the blocks in? for Periodic table/extended - fonzy

I'VE BEEN WAITING AGES FOR A REPLY ON THIS. - FONZY


 * It's fine the way it is. Geez, get a grip. --Ed Poor

- at the moment some one them are colour s i did nto chaneg, and teh otehrs are nto tehblock colours tehy are the colours of the groups. - FONZY


 * Well, it looks fine to me. --Ed Poor

I really don't know what to color the blocks fonzy - just choose something that is not the same as any of the colors used for the chemical series. --mav 21:59 Oct 1, 2002 (UTC)

The current colours in the key all look rather similar to me; perhaps it would be nice to have them cover a bigger range. But thinking about it, I'm not sure that colouring by block is particularly useful; I find that the eye divides the table naturally into blocks as it is. I think a colour scheme by (different types of) metal/nonmetal/metalloid as we currently semi-have is actually more useful. --Bth

- the reason it has to be devided by blocks is that no-one knows what the G-block elements are (even where the start, only theories at the moment). - fonzy

Elements above 120

 * WHERE DID ELEMENT 118 go??

I've unlinked all the entries above 120 because, as several places have said, these are only temporary names. Until they've been discovered, we really don't have much to say and after they've been discovered, they'll be renamed - likely for the discoverer. Any article on the new element should be created at that new name. Creating a bunch of red links now will just mean a lot more maintenance later.

There are, of course, exceptions like 118 which was thought to be discovered and then retracted. For reference, here is the list of names and symbols that I touched. Rossami 23:26, 17 Aug 2004 (UTC)


 * Not really. The time between the discovery of an element and it's naming can be decades! For example, it took Rutherfordium THIRTY THREE years to be named. That's why it's important to maintain links to the temporary names (and they can't be named after their discovers because you aren't allowed to be alive and have an element named after you... though if you wait 33 years...). Since they will be used (if the element is discovered), and not renamed for some time, I think we should replace the links. Ctachme 16:30, 18 Aug 2004 (UTC)

I've replaced the link to 126, because it has a theoretical interest. I suggest that the simplest way to approach this is to leave the table as is, and only link in elements which someone has cause to write an article on. Stirling Newberry 19:55, 30 Aug 2004 (UTC)

Poll
This going back and forth is tiring. I strongly support the recent delinking of uncreated articles. Until someone has something to say about it, leave it unlinked.

Content of the poll:


 * Element articles shall only be linked to this page if the article linked 1) exists 2) contains information other than boiler plate material. Elements may have articles even if they have not been detected, if there is information of encyclopediac relevance.

Stirling Newberry 05:18, 25 Feb 2005 (UTC)


 * 1) Stirling Newberry 05:18, 25 Feb 2005 (UTC)
 * 2) There should be an "or" between 1 and 2 above.  If there remains any article on a non-hypothetical element that's only boilerplate, slap a tag on it and recruit some knowledgable people to help.  If there's an article that has legit non-half-assed-guess verifiable information on a not-yet-existent or only-briefly-existent element, it should be kept and improved.  Anything in neither of those two categories, but widely used in theoretical discussions, should be redirected to Transactinide element.  The ones that are nothing more than extensions of the naming system with no cited usage (disregarding Wikipedia mirrors) should be deleted.  Barno 03:23, 28 March 2006 (UTC)

Discovered
This is probably a dumb question, but what is meant by "discovered" in this article? Any other elements that come along are ones that will have been "created" by scientists in a labratory, right? Generally, we don't "discover" things that we artificially make our selves. func (talk) 04:20, 13 Mar 2005 (UTC)

The scientist did indeed create the particular atoms, but the notion of an atom with 116 protons already existed in the platonic sense. What the scientist discovered is that atoms of that element can exist in our universe. So while they "created" the atoms, they "discovered" the element. 140.180.149.219 14:40, 17 October 2006 (UTC)

Is this table needed
I recently created an article on Untriseptium, which gives reasons why elements of atomic number above 138 are unstable. Basically the 1s electrons of elements with atomic numbers higher than this would have to be traveling faster than the speed of light.

Therefore is the table to element 218 needed, considering that one could never generate atoms or ions of them, even if one were able to create a stable central charge. --Neo 22:06, Mar 31, 2005 (UTC)


 * The table in that case should extend to atleast element 139... 132.205.64.91 01:50, 24 August 2005 (UTC)


 * Nuclei of atomic number 139 and above could exist entirely stripped of electrons. Just like H+ or He2+ which have no electrons, this ion would be Uto139+. Some people conjecture that their massive density along with an occasional proton would give neutron stars huge nuclei. Flying Jazz 05:34, 9 December 2005 (UTC)


 * Personally I find the addition of period 9 to be bonkers. Period 8 is bad enough...--feline1 12:14, 20 December 2006 (UTC)


 * As I understand it, even neutral atoms with Z>139 are possible, only we don't yet have the physics to describe them (there is no consistent theory combining quantum mechanics with general relativity). --Roentgenium111 (talk) 19:53, 19 July 2008 (UTC)

Table incorrect ?!
None of the references given shows the extended periodic table as it is given here. In fact, only the first reference mentions it at all, and it gives three different versions of the extended table (one by Seaborg and two by other scientists). Seaborg's version, as given there, puts the f1 column to the left (between s2 and g1). The other (more recent) suggestions for an extended table vary even more from the Wikipedia table. So is there any reference for the Wikipedia version at all?? --Roentgenium111 (talk) 23:27, 9 August 2008 (UTC)

What in heck heck is the point?
Why? Why have a periodic table where nearly half are undiscovered and will remain that way far beyond any of our lives, and maybe are completely unable to exist?

It's folly. —Preceding unsigned comment added by 99.245.254.168 (talk) 17:28, 10 January 2009 (UTC)

Remove highest-numbered elements ?
According to http://www.britannica.com/EBchecked/topic/603220/transuranium-element, it is generally believed that the highest possible atomic number is between 170 and 210. The Rihani reference used for the table only numbers the element boxes until 173. Thus I suggest we remove the element names and numbers from the table for all numbers above a certain limit (e.g. all above 173, or all above 190 (the average of 170 and 210)). Any opinions? --Roentgenium111 (talk) 17:00, 13 January 2009 (UTC)
 * How did scientists studied that the maximum possible atomic number is believed to be between 170 and 210? I think that the highest atomic number should be at least 218 since element 218 is the last element of period 9 and the last in the extended periodic table. BlueEarth (talk | contribs) 17:16, 13 January 2009 (UTC)
 * I don't know how they calculated these numbers, but the Encyclopedia Britannica is surely a trustworthy source. Whereas the extended table with 218 elements, as currently shown on this page, seems to be a Wikipedia invention (the only reference with a 9th period stops numbering at 173).--Roentgenium111 (talk) 12:40, 14 January 2009 (UTC)
 * A vague statement that "The maximum atomic number, according to current theories, lies somewhere between 170 and 210" is not a discussion of the depth or clarity that induces confidence. I do not consider the EB a sufficiently reliable source for contemporary science, as compared with actual scientific works, and I think we need better citations than that.  Even if this is pure speculation, there may be as ource for the speculation being notable.  DGG (talk) 20:46, 19 January 2009 (UTC)
 * What exactly is vague about the statement? I'm happy if you can give other sources. But currently, we do not have a single source for a periodic table with more than 173 elements, other than the EB. Thus, the higher elements must be removed by WP:OR. --Roentgenium111 (talk) 21:16, 19 January 2009 (UTC)

I have now deleted the elements above 210, since there is no reference for their inclusion in the extended table and they cannot exist (at the current state of knowledge) according to the EB reference given above. --Roentgenium111 (talk) 18:41, 22 January 2009 (UTC)

Super-extended periodic table
If we add two more periods to the extended periodic table, then there would be an another theoretical block called the h-block, which will have 22 elements in each row, and the total number of elements in periods 10 and 11 are 72. This periodic table would be called super-extended periodic table, which will contain 362 elements (72×2=144+218=362). BlueEarth (talk | contribs) 23:07, 21 January 2009 (UTC)

Okay... Not taking the Z=173 limit (or relativistic effects) into consideration, then we get Period 10 going from Biunennium (219) to Biennilium (290). Period 11 would then go from Biennunium (291) to Trihexbium (362). What after that? If we have no stopping point (which I think we should at least take into cosideration), then we can go on to Period 12, containing the j-block of 26 elements, which gives us a total of 98 elements per period. If this increases, we would eventually run out of space.

Period 50: Bbneo (22,098) - Btqqe (23,449) [Introduction of u-block]

And now we've run out of letters. Sure, we could talk about Period 52, containing 1,458 elements, along with the Alpha-block (α-block), containing 106, but is there really any point to attempting to predict the chemical properties of Bihexbihexnilium, the 26,260th element on the periodic table with symbol Bhbhn (which, by the way, woul be either a noble gas or a post-transition metal, depending on wheter or not the post-transition metal category will overcome the halogen and noble gas categories as it did with the pnictogens and chalogens)? That's not to say, of course, that I wouldn't like to see us try. I think that this is an idea that should be taken into some serious consideration... Why should we end at 173, anyway? Let's start be following Seaborg's 218 element model. Jacob S-589 (talk) 00:30, 22 September 2013 (UTC)
