Which element does NOT have similar chemical properties to neon (Ne)?

c He

Damon
Helium is correct because it has a full outer shell and therefore is resistant to reacting. The others are active.

I beg to differ. Ne, Xe, He and Ar are all noble gases, and chemically inert.
Fluorine is about as far from that as possible.

Sorry, oobleck is correct. I did not read carefully.
