Oxidation number –

How to determine oxidation number:

1. Fill in the group #, atomic #, # of protons and # of electrons on the chart below.

2. Determine the number of valence electrons for each element.

3. Determine the number of electrons that element needs to transfer.

a. 3 or less valence electrons = LOSE electrons

b. 4 or more electrons = GAIN electrons

4. Determine the overall charge on the atom once the electrons are transferred.

a. ALL ATOMS are neutral to begin with (# of + protons = # of – electrons)

b. If an atom LOSES electrons it will become POSITIVE (cation)

c. If an atom GAINS electrons it will become NEGATIVE (anion)
