Question

Metals conduct electricity due to presence of mobile electrons.

• A. True
• B. False

Answer 1

The correct option is A True

The valence electrons of any material can allow for transmission of EM energy. In metals, they tend to be in relatively consistent lattices and have a lot of available/free valence electrons, making the opportunity and efficiency of electrical conductance high. In things that have similarly efficient lattices but are not conductive, it's due to having little or no free electrons.
