An ionic compound contains a single metal cation and a single non-metal atom. What’s the structure of this molecule? Is this molecule polar or non polar?

Ionic compounds form structure from metals and nonmetals generally. compounds that don't contain ions, however rather comprise of atoms aggregated firmly together in molecules are called covalent compounds.

An ionic compound is a giant structure of ions. These ions have a regular, rehashing course of action called an ionic lattice. The grid is framed in light of the fact that the particles pull in one another and structure an ordinary example with oppositely charged ions close to one another.  

Ionic bonds are framed when there is an extremely high contrast of electronegativity in the components. In this way, one can't express ionic bonds to be polar or nonpolar. Be that as it may, one can say that ionic bonds are similar to polar bonds with the complete exchange of electrons occurring.
