What is the Maximum Number of Electrons in a Single

Question

What is the maximum number of electrons in a single 2 p orbital of an atom?
A) 1
B) 2
C) 3
D) 4
E) 5

Accepted Answer

The maximum number of electrons in a single 2p orbital of an atom is 2. This is consistent with the Pauli Exclusion Principle, which states that no two electrons can have the same set of four quantum numbers. Since each orbital can hold a maximum of two electrons (with opposite spins), the 2p orbital can hold a total of 2 electrons.
