Question

Compare the properties of metals and non-metals with respect to electronic configuration.

• A. Metals have 1,2 valence electrons while non metals have 3,5,6 or 7 valence electrons
• B. Metals have 1 or 3 valence electrons while non metals have 2,5 valence electrons
• C. Metals have 2 or 3 valence electrons while non metals have 1,5,6 or 7 valence electrons
• D. Metals have 1,2 or 3 valence electrons while non metals have 4,5,6 or 7 valence electrons

Answer 1

The correct option is D Metals have 1,2 or 3 valence electrons while non metals have 4,5,6 or 7 valence electrons

Metals have 1,2 or 3 valence electron while non metals have 4,5,6 or 7 valence electron.
