Is ZnS an ionic compound

Answer 1

An ionic compound is formed between a metal and a non-metal. Zinc is a metal and iodine is a non-metal. Zinc needs to lose two electrons in order to have a full outer shell, and iodine needs to gain one electron to have a full outer shell. One zinc atom will form a positive ion (Zn2+), and two iodine atoms will gain one electron each from the zinc atom, forming negative ions (I-). As such, the chemical formula of zinc iodide is ZnI2. The equations below demonstrate this.

Zn --> Zn2+ + 2e-

2I + 2e- --> 2I-

Answer 2

Yes. It contains divalent zinc cations and divalent sulfide anions.

===================

No, the bonds in zinc sulfide have very little ionic character (19% ionic character). The confusion lies is the fact that ZnS has a high melting point (it actually sublimes at 1185C).

The problem is that bonding is vastly oversimplified and any substance with a high melting point or containing a metal and a nonmetal are assumed to be ionic. Such is not the case.

The bottom line is that it is the structure of the substance -- network vs discrete molecule -- that determines properties like MP and BP, not whether the bond is either hypothetically "ionic" or "covalent".

Answer 3

Zinc Chloride is NOT an ionic bond. An ionic bond simply refers to the electrostatic attraction between the positively-charged Zinc and the negatively-charged Chloride ions. Zinc Chloride is an ionic COMPOUND. The reason it is an ionic compound is because Zinc is a metal while Chlorine is a non-metal. Ionic compounds are formed when a metal and a non-metal combine. I hope this removes any confusion of the chemical terms you have.

Answer 4

Yes, zinc fluoride, ZnF2, is an ionic compound. Metals and nonmetals tend to form ionic bonds with one another.

Answer 5

Yes.

Answer 6

Yes, ZnS is an ionic compound. It is composed of zinc ions (Zn2+) and sulfide ions (S2-), which are held together by ionic bonds.
