Answer:
Explanation:
A = A metal that lost three electrons is Z³⁺
Metals loses their electrons and form cations. So when an metal loses three electrons positive three charge is created.
B= A metal that lost one electrons is Y⁺
When metal loses one electron positive one charge is created.
C=A nonmetal that gained one electrons is X⁻
When non metals gain the electrons anions are formed and negative charge is created on atom due to addition of electron. So when non metal gained one electron -1 charge is created.
D= A nonmetal that gained three electrons is V³⁻.
when non metal gained three electrons -3 charge is created, because of addition of three electrons.
