Question

tell me about few lines of energy level and energy band theory​

Answer 1

Answer:

energy level is also called as orbit or shell. some of the shells are K L M N . K should have 2 electrons. N should have 8 electrons. M should have 18 electrons. N should have 32 electrons. this depends on the formula 2n^2. electrons move around nucleus.

energy band theory,in solid-state physics, theoretical model describing the states of electrons, in solid material, that can have values of energy only within certain specific ranges.
