Question

explain aufbau principle Pauli exclusion principle​

Answer 1

Answer:

First, the Pauli exclusion principle lets us know that no two electrons can have the exact same quantum numbers. This means that two electrons in a single orbital must have opposite spins. ... Finally, the Aufbau Principle states that electrons fill lower energy orbitals before moving to higher energy orbitals.
