Explanation:

Inert elements like argon are noble gases. Noble gases have a full valence electron shell, which makes them very stable and unreactive. Option A states they don't react with other elements to form compounds, which aligns with their inert nature. Option B is incorrect as they don't easily react. Option C is wrong because in a neutral atom, protons equal electrons. Option D is incorrect as they don't lose outer electrons since their outer shell is full.

Answer:

A. They don't react with other elements to form compounds.
