Question

Which properties of solids are explained by electron gas theory

Answer 1

Answer:

 solid-state physics, the free electron modelis a simple model for the behaviour of charge carriers in a metallic solid. It was developed in 1927,[1] principally by Arnold Sommerfeld who combined the classical Drude model with quantum mechanical Fermi–Dirac statisticsand hence it is also known as the Drude–Sommerfeld model.
