Talk:Group 12 element

A few ideas

 * Zn is similar with Mg.


 * "not transition elements as the d-shell is full." I thought that both including and excluding from TM is common. MAYBE this question is worth a separate subsection.


 * Make the table in Physical illustration to the text, not the text (just write something)


 * Once again MAYBE an explanation why Hg is liquid will be helpful.


 * History is very short. What I want it to be is Group 3 element (of course I wrote it myself), but it's nothing but a point of view. (The article may be helpful at all, you may also check noble gases)


 * Maybe you could note that group 12 was IIB before? Earlier, didn't anyone try to characterize the similarity between the elements (triels or something)?


 * How much Cd and Hg has been made/is made per year?


 * Applications may be enlarged. Aren't there uses for Hg?


 * I ain't sure, but isn't there some microscopic amount of Cd and Hg in humans? Just if there's some of any lanthanide (but Pm), there may be also Cd/Hg traces.


 * "Like in most other d-block groups the abundance in Earth's crust decreases with higher atomic number, and so the zinc is with 65 parts per million (ppm) the most abundant in the group while cadmium with 0.1 ppm and mercury with 0.040 ppm are orders of magnitude less abundant." Hmmm, these numbers say nothing to almost anyone. SO Zn is common, Hg is among rarest of all (right?), and Cd doesn't seem to be very common as well.


 * "While mercury and zinc minerals are found in large enough quantities to be mined, cadmium is too similar to zinc and therefore is always present in small quantities in zinc ores." Wait a minute, Cd is more common than Hg. I guess it's because Cd is similar with Zn, and Hg is separate from them. If I'm right, this'll have to be included.

There may be more, that's what I found after reading this once. All of the above is only my opinion--R8R Gtrs (talk) 10:09, 29 August 2011 (UTC)

Common structural properties
The elements 30Zn, 48Cd. 80Hg, and and 112Cn all have the common feature of being the last element of a 10 element (2 + 4 + 4 = 10) so called transition metal series which then is extended by a 6 element (2 + 4 = 6) series to the end of the IUPAC table. This implies the end of the creation of a 10 element structural feature of the atomic nucleus. And this structural feature is related to the fact that it is concerned with the minimum addition of 10 deuterons plus some extra neutrons to the nucleus, with each of the incremental elements being changed by the addition of a single deuteron. — Preceding unsigned comment added by WFPM (talk • contribs) 18:48, 22 November 2012 UTC
 * Moved from GA review page --Tito Dutta (talk) 19:58, 22 November 2012 (UTC)

The range of the number of excess neutrons required for the stability of the elements of this group is from 4 to 10 for 30Zn, from 10 to 20 for 48Cd, and from 36 to 44 for 80Hg, with the central stability isotope of 80Hg lying on the isotope stability line with the formula A = 3Z - 40 = EE80Hg200, with 23% constituency. There are no stable isotopes of 112Cn, probably due to a high probability of alpha particle emission instability. However a trend line related to a minimum of instability would probably be that involving the existence of a 4n number of extra neutrons and thus being in the range of A = 3Z -40 (at EE112Cn288 with 64 extra neutrons) or A = 3Z - 44 (at EE112Cn292 with 68 extra neutrons). The reported data is only for isotopes up to EO112Cn285 with 61 extra neutrons, and may indicate the inability of the structure to accumulate extra neutrons beyond a maximum number.WFPM (talk) 02:35, 26 November 2012 (UTC)

Move discussion in progress
There is a move discussion in progress on Talk:Group 3 element which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 21:15, 15 January 2013 (UTC)

RfC: Colour group 12 as post-transition metals
I am seeking comments on a proposal to color code the group 12 elements as post-transition metals in the Wikipedia periodic table, rather than transition metals as they are currently color coded.

The RfC can be found here. Sandbh (talk) 23:11, 9 August 2017 (UTC)

Is Hg the “only” metal that is a liquid at room temperature
Fr also is, since its melting point is only 297K (about 300K). — xayahrainie43, 2018. 09.01 10:59
 * The melting point of Fr is only a guesstimate according to our article on that element. We can't say anything in an article that isn't citeable to a reliable source. DMacks (talk) 09:13, 1 September 2018 (UTC)

If we know so much about Cp, then why are all these tables for Cp blank? Porygon-Z 15:26, 26 November 2018 (UTC) — Preceding unsigned comment added by Porygon-Z474 (talk • contribs)
 * First of all, it is Cn, not Cp. Second of all, we really do not know all that much about Cn; most of what is written there is in fact only predicted, as it must be as long as we have no way of making it in bulk quantities. Double sharp (talk) 15:48, 26 November 2018 (UTC)

Zink topic
Why zink is included in d block transition metal group? 103.113.172.5 (talk) 05:28, 18 December 2021 (UTC)
 * Not sure if I'm understanding your question, but zinc is in group 12 in the d-block because it has a d10 s2 electron configuration. ComplexRational (talk) 15:52, 18 December 2021 (UTC)
