Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).

What kind of charge does the element calcium have?

Calcium typically forms a +2 charge by losing its 2 valence electrons.


If calcium has two valence electrons and sulfur has six how many calcium?

In a chemical reaction, calcium (which has two valence electrons) typically forms a +2 charge when it loses its two electrons, while sulfur (which has six valence electrons) typically forms a -2 charge when it gains two electrons to achieve a stable octet. Therefore, one calcium atom can bond with one sulfur atom to form calcium sulfide (CaS). In summary, one calcium atom is needed to balance the charge of one sulfur atom.

How many electrons must calcium gain or lose to have 8 valence electrons and what charge of the ion will it make?

Calcium has two valence electrons and needs to lose both to achieve a stable electron configuration, resulting in 8 valence electrons in the nearest noble gas configuration (argon). By losing these two electrons, calcium forms a cation with a charge of +2, resulting in a Ca²⁺ ion.
