Talk:Atomic number

"Atomic Number (Z)"
Why it is Z? or not for example M or P? Thx in advance for answering me. Martin from Poland.
 * I was looking at other sources and I cannot find a reason for any letter to be placed after the atomic number - there is no unit. GotPSP 21:56, 31 January 2007 (UTC)


 * Maybe it is because the German word for number begins with a Z, but I'm just guessing. Itub 08:39, 8 March 2007 (UTC)


 * nope, the german word for number is number, oddly enough. Z could just be the random letter they picked.--Scorpion451 20:24, 16 June 2007 (UTC)
 * German has more than one word for 'number', Nummer is one (two 'm's, no 'b'), and Zahl another. Connoissaur (talk) 11:00, 1 February 2024 (UTC)
 * However the German word for integer is zahlen. See integer which zahlen redirects to. This may be relevant as the atomic number is of course an integer. I concur with the next comment, Z is not a unit, merely a symbol, similarly A and N. I would assume A comes from atom and N comes from neutron. It doesn't hurt to think of it this way if it helps you remember which is which.Puzl bustr (talk) 08:50, 31 October 2009 (UTC)
 * The German word for 'integer' is Ganzzahl. Zahlen with a capital 'Z' means 'numbers' and can therefore be used informally to mean 'integers' (plural); zahlen with a lower-case 'z' means 'to pay' (whereas zählen means 'to count). Connoissaur (talk) 11:04, 1 February 2024 (UTC)


 * Z is not the unit of the atomic number it is the variable that stands for the atomic number, for example: for hydrogen Z=1. "m" is used as the magnetic moment for atomic orbitals and "p" is a type of orbital, since all of these terms are used together when referring to the structure of an atom they must have different symbols. --Whmice (talk) 11:43, 22 March 2008 (UTC)

Atomicity
Why does this article include a paragraph on atomicity? Should it be expanded into a section that ties in with Z? (And if so, how?) Or would anyone mind if I just deleted it? Querl 02:46, 21 February 2007 (UTC)
 * I had a similar thought when I did a cleanup of the article. The paragraph seems like it belongs in some article, but it wasn't immediately apparant to me which one. It's more closely related to molecules than to atomic number. -- Mainstream Nerd 03:48, 21 February 2007 (UTC)

Confusing diagram
The diagram that appears at the head of this article is confusing and requires amending: https://commons.wikimedia.org/wiki/File:Atomic_number_depiction.svg Specifically, the text in the upper-right seems to indicate that the superscript number is the "Atomic / mass" number, as if these terms were interchangeable, but they are not. The superscript digit shows the mass number, the subscript digit the atomic number. Connoissaur (talk) 10:55, 1 February 2024 (UTC)
