What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

How do you determine the formula of an ionic compound?

Back

To determine the formula of an ionic compound, combine the cation and anion in a ratio that results in a neutral charge.

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion, while an anion is a negatively charged ion.

What is the significance of the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to the formation of stable ionic compounds.

What is lattice energy?

Back

Lattice energy is the energy released when ions in the gas phase combine to form an ionic solid.
