Question

The expected energy of the electrons at absolute zero is called?

Answer 1

Absolute zero:

1. Absolute zero is the temperature at which particles emit the least amount of heat.
2. It is zero on the Kelvin scale, an absolute zero is also known as the zero kelvin.
3. The highest energy level in the valence band that an electron can occupy at $0K$ is known as the Fermi energy level.

Thus, the Fermi energy level is the expected energy of the electrons at absolute zero.
