Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.

How do you know if an ionic compound between an alkali metal with a nonmetal is done correctly?
Since all alkali metals form a 1+ ion, the number of alkali metal atoms in the formula should be equal to the charge on the negative ion.
Does CaCl2 contain an alkali metal and a halogen?
Calcium chloride contains an alkali earth metal (calcium, a group 2 element) and a halogen (chlorine). There is no alkali metal. Alkali metals are group 1 elements.
