What does valence refer to in chemistry?

Explanation:
Valence is the combining power of an element—the number of bonds it tends to form with other atoms. This comes from the electrons in the outermost shell, which atoms gain, lose, or share to reach a stable, often full, configuration. For example, hydrogen tends to form one bond, oxygen typically two, and carbon can form about four bonds in many compounds. The other options describe physical properties (color, density, melting point) and don’t determine how an element bonds, so they don’t define valence.
