i. Na(SO)4
ii. Ca2Cl2

Answer 1

Answer:

1) Na2SO4

2) CaCl2

Explanation:

To get the right formula look for ionic numbers of these atoms like Sodium or Na have 1 extra electron so it's ion is +1 because to become stable it loses 1 electron hence +ve charge. Here you don't need to give attention to signs though.

Answer 2

Answer:

Chemical Formula
