The formula for Potassium Sulfide is K₂S.

Front

What happens to an atom when it loses an electron?

Back

When an atom loses an electron, it becomes a positively charged ion (cation).

Front

What happens to an atom when it gains an electron?

Back

When an atom gains an electron, it becomes a negatively charged ion (anion).

Front

Front

How do you determine the formula of an ionic compound?

Back

To determine the formula of an ionic compound, balance the total positive and negative charges of the ions.

Front

What is the significance of valence electrons in ionic bonding?

Back

Valence electrons determine how an atom will bond with others, including the formation of cations and anions.
