Question

The probability of an energy state below the Fermi level being occupied by an electron is :

Select one:
a. More than 50%
b. Equal to 100%
c. Less than 50%
d. None of these

Answer 1

The probability of an energy state below the Fermi level being occupied by an electron is 100%.

Step-by-step explanation:

The probability of an energy state below the Fermi level being occupied by an electron is 100%.

At T = 0 K, the Fermi energy, denoted as Ef, represents the highest energy level occupied by the electrons in a metallic solid. Any energy state below the Fermi level will be occupied by an electron. This is because of Pauli's exclusion principle, which states that no two electrons can be in the same quantum state.

Therefore, the correct answer is b. Equal to 100%.
