Yes they can form ionic compounds
No. They will make covalent compounds as in ICl or ICl3.
Yes. The ionic compounds make ions
- If you think only to isolated elements all these elements can form polyatomic compounds.- Calcium and sodium form ionic compounds.- H, N, O, Cl can form ionic or covalent compouds.
because Na passes it electron of its last shell to cl and follows octet rule thus an ionic compound na-cl+ is formed
Iron(III) chloride,
Metals form ionic compounds with non metals. Fe is a metal. So it is likely to make ionic bonds with Cl.

Common salt is NACl and contains both sodium and chlorine. It can therefre be used as a source of chlorine (electrolysis) and sodium compounds.
Sodium chlorine sodium and chlorine.

Iron(III) chloride,
Iron chlorides are FeCl2 and FeCl3.
Chlorine and carbon
Salt.
Iron chloride (FeCl2 or FeCl3) would have to be considered as a COVALENT compound. The reason for this is that the Cl has an electronegativity (EN) value of 3.16 and Fe has an EN value of 1.83. The difference is 1.33, and it is widely accepted that to be ionic, the EN difference should exceed 1.7. Of course, iron chloride will have some ionic character, but it should more properly be classed as a polar covalent molecule. Just because it is a metal bound to a non metal, does NOT make it ionic. This is a fallacy.
