Answer:

Calcium can lose 2 electrons to make the ion calcium, following this equation:

Ca → Ca2⁺  + 2e⁻

Explanation:

Calcium is the third element of group TWO in the periodic table. As it belongs to group two, it means that can lose 2 electrons to get the noble gas configuration that corresponds. It is a metal from the group of alkali earth metals.  

Since its tendency is to lose electrons, it is said to form charged ions (+)
