Ionic compounds are between metals and non-metals. Molecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals.)

An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state.

A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state.

Another important difference between the two is that an ionic compound is a crystalline solid at standard temperature and pressure (STP), whereas a molecular compound can be in a solid, gas or liquid state at STP.

Molecular compound is derived from combinations of different molecules while ionic compound is derived from inducing electrical current into molecules.

if the compound contains a metal bonded to a nonmetal, it is most likely an ionic compound. It the compound contains two nonmetals, it is a molecular compound.

It is ionic compound as the difference in the electronegativity between chromium and oxygen is more than 1.7

Ionic compounds contain ionic compounds whereas molecular compounds contain covalent bonds in their molecules.

Yes, if the microscope's enlargement ability is adequate, you can see the crystalline structure in ionic compounds unlike in molecular compounds.

Molecular. The bonds form between 2 nonmetals. Ionic bonds form between metals and nonmetals.

Ammonia is a molecular compound and not ionic.
