Q. What is the name of the ionic compound ZnS?
Zinc sulfide, ZnS, occurs in nature as the mineral sphalerite and may be prepared by treating solutions of zinc salts with hydrogen sulfide.
Q. Is ZnS a ionic compound?
The Compound ZnS Is An Ionic Compound.
Q. What type of compound is ZnS?
Zinc sulfide
Q. Why is ZnS covalent?
The chemical structure of ZnS is simple and consists of the zinc metal attached to a sulfur atom through a polar covalent bond. Solid zinc sulfide is found in two different crystal forms, alpha (wurtzite) and beta (sphalerite), which have hexagonal and cubic structures, respectively.
Q. Why ZnS is ionic?
It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio. Since the number of atoms in a single unit cell of Zn and S is the same, it is consistent with the formula ZnS. The ionic radius for Zn2+ is 74pm and for S2- is 190pm.
Q. Is ZnS a covalent crystal?
The crystal structures of covalent crystals have: diamond (tetrahedron, i.e., diamond, Si) zinc blende; wurtzite (i.e., ZnS, ZnO, HgS, and CuCl); and silicate (i.e., quartz crystal) structures.
Q. Is ZnS covalent or ionic?
Zinc sulphide is an ionic compound. It is composed of Zn2+ and S2− ions.
Q. What is a ternary ionic compound?
Ternary compounds are composed of three different elements. The most common types of ternary compounds consist of a metallic cation (positive ion) and a polyatomic anion (negative ion). The only common polyatomic ion with a positive charge is the ammonium ion.
