1. How many more electrons can fit in the valence shell of a hydrogen atom?

2. The valence electron of a sodium atom does not sense the full 11⁺
charge of the sodium nucleus. Why not?

3. How is the number of unpaired valence electrons in an atom related to the number of bonds that the atom can form?
