Feb 2, 2014

In the ionic bond formation between calcium and sulfur, a calcium atom donates two valence electrons to a sulfur atom to form a Ca2+ ion and an S2+⁻ ion.

Explanation:

A Ca atom has two valence electrons. It can achieve a noble gas configuration by losing these two electrons.

CaCa
(From Quora)

A sulfur atom has six valence electrons. It can achieve a noble gas configuration by gaining two electrons.

SS

If Ca gives two electrons to S, both ions have a noble gas configuration.
