Which of the following electron configurations violates the Pauli exclusion principle?
- A 1s^2 2s^2 2p^6
- B 1s^2 2s^2 2p^5
- C 1s^2 2s^2 2p^3
- D 1s^2 2s^2 2p^4
That's Correct!
It's Wrong!
The electron configuration 1s^2 2s^2 2p^3 violates the Pauli exclusion principle because two electrons are supposed to occupy the 2p orbital, each with opposite spin. In this configuration, three electrons are present in the 2p orbital, which is not allowed as per the exclusion principle.
