Multiple choice

Which of the following is a chemical property of metals?

  1. Gain electrons easily

  2. Good oxidizing agent

  3. Form oxides that are basic

  4. Highly electronegative

C Correct answer
Explanation

Metals react with oxygen to form basic oxides because they are electropositive elements that readily lose electrons. This is a key chemical property distinguishing metals from non-metals, which typically form acidic or neutral oxides. Option A is incorrect because metals tend to lose electrons (not gain). Option B is wrong because metals are reducing agents (not oxidizing agents). Option D is false because metals are electropositive (not electronegative).
