Explain the mutual exclusion principle.
1 Answer
Sudheesh Singanamalla
In an atom or a molecule two electrons can not have the same parameters. Example in an atom , the electrons are in orbital characterized by 4 parameters 3 quantum numbers n, l, m characterizing the orbital and one the spin which is +1/2 or-1/2 depending on the sense of rotation on the electron about its axis.The exclusion principle states that given 2 electrons ,they can not share all 4 same quantic numbers
Mutual Exclusion principle is the same as Pauli's exclusion principle.
It states that an atom cannot have the same set of quantum numbers in its electronic configuration.
Please approve !
