Complete reviewing the HW questions assigned.
Discuss how cations are formed, the position on the periodic table where atoms are found that produce cations. Discuss the formation of +2 and +3 ions by the transition metals, and how they are indicated on paper.
Show how anions are formed by the acceptance of electrons, usually into the s and p sub shells in the last primary quaantum energy level.
List group numbers 15,16,17, the number of valence electrons in each group, and how many electrons can be added to each atom in the different groups to produce an anion.
Define binary ionic compound and oxide.
Use examples to prove that in binary compounds, the net electric charge must be zero.
