Ionic compounds can be made from a metallic ion and a nonmetallic ion. metallic ions are positive (cations). nonmetallic ions are negative (anions). for each equation given below, enter the sum in the space provided.

(+1) + (–1) =

(+2) + (–2) =

2(+1) + (–2) =

(+3) + 3(–1) =

3(+2) + 2(–3) =

Explanation:

Since metals have more number of electrons therefore, they donate extra electron(s) in order to gain stability. Whereas non-metals have less number of electrons than metals. Hence, non-metals readily gain electron(s) in order to gain stability.  

Sum for the mentioned entries are as follows.
