Question: How do atoms share more than one pair of electrons?

Observe: Like fluorine and most other elements, oxygen atoms are most stable with a full complement of eight valence electrons.

A. How many valence electrons does each oxygen atom have now?


\
B. How many more electrons does each oxygen atom need to be stable?
