Answer 2

Answer:

(a) A material possessing a moderate band gap.

Explanation:

• A metal is said to be within band theory when it conducts electricity with the help of valence electrons within them.

• The energy band gaps in metals that conduct electricity have small or moderate band gap which helps in the excitation of the electrons present in them.
• Metal within band theory is said to be a material possessing a moderate band gap.
