Explanation / Answer

Ionic compounds: ionic compounds are formed betwen metal and Nonmetal.

Molecular compounds: molecular compounds are formed betwen non metals.

Metals always form actions and Nonmetal always form anions.

Part I:

CuCl2 it is an IONIC compound.

CuCl2 ------> Cu2+ 2Cl-

Hence correct options are

Calcium is cation (Ca2+)

Chloride is an Anion (Cl-)

Part 2:

Ca3(PO4)2 -------> 3Ca^2+ + 2PO4^3-

The correct options are

Calcium is a cation (Ca2+)

Phosphate (PO4^3-) is polyatomic anion.

Part 3:

N2O3: this compound is composed of two non metals. So it is MOLECULAR compound. So it will not form cation and anion.

Hence correct option is

It would be named as molecular compound.
