How is electron movement related to the bonding in sodium chloride?

Back

Electrons exchange creating ions to form an ionic bond.

Front

What is the difference in oxidation #'s and valence electrons?

Back

Valence electrons are the electrons in the outermost energy level and oxidation #'s tell the charge of an ion after electrons are gained or lost.
