Answer: Option (B) is the correct answer.
Explanation:
An atomic orbital is defined as the space around the nucleus of an atom where electrons are located.
The first orbital around the nucleus is known as K-shell. The second orbital is known as L-shell. The third orbital is known as M-shell and so on.
The first orbital of every atom can hold up to 2 electrons only.
Whereas all other orbitals can hold up to a maximum of 8 electrons.
Thus, we can conclude that the maximum number of electrons that an atomic orbital can contain is 8.
