this may not be what you are looking for but Carbon is an exception in being the only one that does not have a full shell of 8 in its electron structure

It goes 2-4
and the others go 2-8-something-...

Silcon is semi-metallic, the rest are non-metallic.

Phosphorus

The others can be found in a pure state, but phosphorus is too reactive and has be be separated?

Those answers are right, but not what I am looking for. I am looking for an answer that is not scientific, more language based.

The only other thig I can think of is that they were all named by they're discoverers except Carbon which had been known since ancient times?

I will hazard a guess. (just a guess...don't kill me ):

Phosphorus

Because the word is derived from two words ( phos (light) and phoros (bearer))
instead of from one word like the others.

He said it was language-based....

Holy moly, i think i got it:

Iodine is the one that doesn't fit

Reason:

Its the only one you can spell with the atomic symbols


C-Ar-B-O-N
Ne-O-N
Si-Li-C-O-N
P-H-O-S-P-H-O-Ru-S
Xe-N-O-N

Dude, i got too much time on my hands!
