The name of the cation usually comes first in the name of an ionic compound.

This would be true. Cations are positive and positive ions are written first.

Monatomic cations bear the same names as their elements, with the addition of the word ‘ion’. For example, Na+ is called the sodium ion, and Ca2+ is called the calcium ion. What do you call a Na2+ ion or a Ca+ ion? Well, Na2+ and Ca+ are not stable ions in solids or solutions. Therefore, whenever one mentions these ions, we know that the sodium ion is always Na+, and the calcium ion is always Ca2+. Some of the cations that have only one stable form are listed in Table I. Notice that if you refer to the periodic chart, with no exception, all the Group IA metals (alkali metals) have a +1 charge, and the Group IIA metals (alkaline earth metals) have a +2 charge. This is due to the ground-state electron configurations of these elements, a topic you will learn about in the Chem 111A lectures in the near future. Other common metal cations that have only one stable oxidation state are: Al3+, Ga3+, Ni2+, Zn2+, Cd2+, and Ag+.

That is true because that is the metal and it goes before the nonmetal.

True, I think.
