NGSS.HS-PS1-2

Which atom pictured needs one more valence electron to be stable?

• A: Hydrogen

• B: Carbon

• C: Oxygen

• D: Fluorine

Answer explanation

Fluorine needs one more electron to make a full valence orbital (8 electrons).

Hydrogen also needs one more electron, because it is stable when having 2 valence electrons.
