One could also answer "Argon" because the other words begin with consonants.

COOL BRAINTEASER!!
Nice teaser!!!
I enjoyed this because it proved I can remember something from Chem classes 3 decades ago - but it's not a very creative teaser. Good for a quickie, though. Oh - almost 4 decades ...
That wasn't that hard. I know little about chemistry and stuff like that but could easily figure it out.
That was easy.
