Question

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) =

Answer 1

all the answers in the equation above will be Zero (0)

Answer 2

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.

• (+1) + (-1) = 1 -1 = 0

• (+2) + (-2) = 2 - 2 = 0

• 2(+1) + (-2) = 2 - 2 = 0

• (+3) + 3(-1) = 3 - 3 = 0

• 3(+2) + 2(-3) = 6 - 6 = 0
