Front

What happens during the reaction H + Cl --> HCl?

Back

A bond is formed and energy is released.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains electrons.

Front

What occurs to anions during ionic bonding?

Back

Anions gain electrons, becoming negatively charged.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses electrons.
