Nickel (II) sulfate forms ionic bonds. In this compound, nickel (Ni) donates electrons to the sulfate (SO4^2-) ion, creating electrostatic attractions between the positively charged nickel ions and the negatively charged sulfate ions.
FeNi is an intermetallic compound with a metallic bond. In this case, the bond between iron (Fe) and nickel (Ni) is considered metallic rather than ionic or covalent.
No, NiSO4 is not covalent. It is an ionic compound because it is composed of a metal, nickel(Ni), and non-metal, sulfur(S) and oxygen(O). Ionic compounds are formed through the transfer of electrons between the metal and non-metal atoms.
No, it is Ionic.
No. The electronegativity difference is 0.67, giving Ni - S bonds 11% ionic character. The bonds have substantial covalent character, instead. The high melting and boiling points of NiS can be attributed, not to the ionic character, but to the network arrangement of atoms. Networks, whether they be predominately ionic or predominately covalant, have higher melting and boiling points.
Ferrous sulfate is both ionic and covalent: The iron cations and polyatomic sulfate anions are ionically bonded, but the internal bonds within the sulfate anions are covalent.
Nickel sulfate is an ionic compound though it has covalent bonds within the sulfate ion itself.
FeNi is an intermetallic compound with a metallic bond. In this case, the bond between iron (Fe) and nickel (Ni) is considered metallic rather than ionic or covalent.

No, nickel sulfide does not have covalent bonds. Nickel sulfide typically forms ionic bonds due to the difference in electronegativity between nickel and sulfur.
Copper (II) sulfate is ionically bonded.
Metallic bonds form between nickel and other metal atoms - sort of metal nuclei in a lattice in a shared cloud of electrons - or if you will - very diffuse covalent bonding. The metal-carbon bond in organometallic compounds is generally of character intermediate between ionic and covalent. In metalorganics (where the metal does not bind directly to the carbon, but to some other atom in the otherwise organic molecule) the bonds tend to be covalent. Between nickel and halogens, the bonds have ionic character. In nickel salts like nickel sulfate, the bonds are ionic. So - in short - the type of bond nickel forms depends on its valence state and what it is bonding with.
Nickel phosphate is an ionic compound.
Carbon dioxide is a covalent compound.
