which of the following violates the pauli exclusion principle?
a
b
c
d
c
d
a
b

Explanation:

The Pauli - exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers. In orbital - filling diagrams, this means that each orbital can hold a maximum of 2 electrons with opposite spins. Option D violates this principle as it has two electrons with the same spin (both up - arrows) in the same orbital.

Answer:

D
