Which of the following is true regarding the metallic nature of minerals? I. Metallic nature is directly proportional to electropositive nature. II. Metallic nature in period increases. III. Metallic nature in groups increases. Correct Answer 1 and 3 only

The correct answer is 1 i.e 1 and 3 only.

  • Metallic nature is directly proportional to electropositive nature. Hence, I is correct.
  • Metallic nature in period decreases. Hence, II is incorrect.
  • Metallic nature in groups increases. Hence, III is correct.
  • Metals lose electrons and are of reducing nature.
  • Increase of nuclear charge decreases the tendency to attract electrons.
