Which of the following has a greater affinity for oxygen: a. Na b. K c. H d. Mg

Explanation

Affinity for oxygen refers to how readily an element or compound combines with oxygen.

Magnesium (Mg) is a highly reactive alkaline earth metal that readily loses its two electrons to form a positive Mg2+ ion.

This ion then readily combines with oxygen to form magnesium oxide (MgO), demonstrating a strong affinity for oxygen.
