Ionic and Molecular Compounds
Ionic compounds are between metals and non-metals.
Molecular 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.
