Question

Which electrons are easy to create as free electrons?

• A. Electrons in the first shell
• B. Electrons in the outermost valence shell
• C. Electrons present beyond the valence shell
• D. All of the above

Answer 1

Answer: (B)

Electrons in the outermost valence shell

Electrons present in the orbit beyond the valence shell are very weakly attracted by the nucleus. Therefore it is easy to remove these electrons using an electric charge. These electrons are called free electrons.
