Which of the following electron configurations violates the Pauli exclusion principle?
- A 1s1
- B 1s2
- C 2s2 2p6
- D 2s2 2p5
That's Correct!
It's Wrong!
The electron configuration '2s2 2p5' violates the Pauli exclusion principle. This principle states that no two electrons in an atom can have the same four quantum numbers, meaning they must have opposite spins. In this configuration, two electrons are paired up with the same spin in the 2p orbital, violating the principle.
