Polar bond between H and I in HI
Covalent
According to two Wikipedia articles, phosphorus and iodine can form phosphorus triiodide (PI3) and diphosphorus tetraiodide (P2I4). These compounds are made from the covalent bonding between the phosphorus and iodine atoms. Nonmetals tend to form covalent bonds with other nonmetals.
An ionic bond - sodium and iodine form NaI, containing Na+ and I- ions.
no, they form covalent bond as the difference in electronegativity between P and H is below 1.7
No, metallic bonds only form between the atoms of a metal. Nitrogen and phosphorous are both nonmetals, and would be expected to form a covalent bond. However, I do not know if nitrogen and phosphorus bond with one another, since they are in the same group.

Bromine
Iodine and Carbon form a covalent bond. Moreover, this bond is nonpolar. Cheers, Caroline

Yes. Nitrogen and phosphorus would form a covalent bond.
An ionic bond - sodium and iodine form NaI, containing Na+ and I- ions.
Yes. Phosphorus in its elemental form can com in the form of P4 molecules (white phosphorous) or as a covalent network (red and black phosphorus)
Magnesium and iodine react to form the ionic compound magnesium iodide - MgI2.
no, they form covalent bond as the difference in electronegativity between P and H is below 1.7

It forms a covalent bond.
