An atom of oxygen has six valence electrons. In nature, oxygen is a diatomic molecule and is usually found in the form O2. Why would one atom of oxygen want to bond with another one? A) When the oxygen atoms bond together, they become ionized.

B) The transfer electrons to each other so they both have a full shell of valence electrons.

C) When oxygen atoms share electrons the outer shell of electrons is filled and each atom becomes more stable.

D) A single atom of oxygen is very stable and simply joins with another oxygen in order to destabilize both of them.
