Properties of Ionic and Covalent Compounds

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. It typically consists of a metal and a nonmetal.

Front

What is a molecular compound?

Back

A molecular compound is a chemical compound where atoms are bonded together by covalent bonds. It usually consists of nonmetals.

What is the typical melting point of ionic compounds?

Back

Ionic compounds generally have high melting points, often above 300°C.

What is an example of a molecular compound?

Back

Dihydrogen monoxide (H2O) is a common example of a molecular compound.

Front

How do ionic compounds conduct electricity?

Back

Ionic compounds conduct electricity when dissolved in water or melted, as the ions are free to move.

Front

How do molecular compounds conduct electricity?

Back

Molecular compounds generally do not conduct electricity because they do not have free ions.
