What is the valence of an element?
The number of electrons an atom must gain, lose, or share to have a full or stable outer electron shell
What does the octet rule state?
Outer electron shells prefer to have eight electrons, even if the shell may not be full
How do you calculate the oxidation state of an element in a molecule?
Determine the oxidation state of all elements forming the molecule except the element of interest, and ensure the sum of all oxidation states equals zero or the net charge on the molecule
