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.

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when molten or in solution.

Front

What is lattice energy?

Back

Lattice energy is the energy released when one mole of an ionic crystalline compound is formed from its gaseous ions.

Front

Why do ionic compounds have high melting and boiling points?

Back

Ionic compounds have high melting and boiling points due to the strong electrostatic forces of attraction between the oppositely charged ions.

Front

How do ionic compounds conduct electricity?

Back

Ionic compounds conduct electricity when they are dissolved in water or melted, allowing the ions to move freely.

Front

What is the difference between a covalent bond and an ionic bond?

Back

A covalent bond involves the sharing of electron pairs between atoms, while an ionic bond involves the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What factors affect lattice energy?

Back

Lattice energy is affected by the charge of the ions and the distance between them; higher charges and smaller distances result in greater lattice energy.

Front

What is the significance of the solubility of ionic compounds in water?

Back

The solubility of ionic compounds in water is significant because it allows them to dissociate into ions, which can then conduct electricity.

Front

What is the role of free electrons in conductivity?

Back

Free electrons are responsible for electrical conductivity in metals, but ionic compounds conduct electricity through the movement of ions.

Front

Which ionic compound has the highest lattice energy: NaCl, MgO, LiBr, or CaF2?

Back

MgO has the highest lattice energy due to the greater charge of the Mg2+ and O2- ions compared to the others.
