    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?

    for whatever reason, carbon
    Greg just asked which element doesnt belong, not why:wink:

    i'll give another hint in a little bit if no one guesses correctly

    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....

    neon - it is the only one that isn't next to another element in the list

    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!
