Only letter not on peridoic table of elements

[mollykins]

I was doing some revision, and whilst looking on a periodic table of elements i realised that there is no j on the p.t.o.e. I am i right or did i miss something, i'm sure i checked the lanthanoids and actinoids aswell, am i correct, and is there another letter that doesn't appear on the table?

[novalis]

You are right.

It's surprising how often it occurs as a quiz question.

I was at a quiz the other week and this was asked. We had to name the letter AND the only English or Scots football team that that used that letter.

Q is only there as a temporary name (ununquadium) and will disappear as soon as an internationally agreed name is chosen.

[ABerrant]

Furthermore, in the event of the adopted IUPAC name and symbol for 114 Uuq not containing Q, and the IUPAC name and symbol for 113 Uut (Ununtrium) becoming Japonium (Jp), the disappearance of Q and appearance of J would require a quiz question rewrite.

This is, of course, ignoring any effects of the naming of Uup, Uuh, Uus & Uuo (synthetic elements 115 to 118) and any other future synthesised elements .

Its a bit odd, did they jsut forget about j, or is there lots of languages that use latin characters, that don't have a j, so it would confuse them?

[beejay1124]

ABerrant- i couldnt have worded it any better myself ^

[Laasya]

yes

Iust cojncjdence, J expect, mollykjns. They don't name elements wjth qujz questjons jn mjnd.

@mollykins - "did they jsut forget about j, or is there lots of languages that use latin characters, that don't have a j, so it would confuse them?"

Perhaps they thought that, what with j already being the mysterious square root of -1 and the basis of the entire complex number system, it already had enough on its plate.

[mollykins]

No but say german didn't have a j in its language, they wouldn't be able to do stuff on the computer with a element that had a j in it, i.e. google it.

But, for example, do china and japan still use Pb for lead, or the equivilent of p and b in their alphabets?

Ah, but 'j' isnt really the square root of -1, 'i' is. Its only 'j' because the symbol i was already in use in electronics (for current) that 'j' was substituted in, in that particular arena to avoid confusion.
Also we know that any number has 2 square roots, e.g. 4's are 2 and -2. so what is the other square root of -1?
