Any two-electron in an atom can have a maximum of three Quantum numbers same.
Any two-electron in an atom can have a maximum of three Quantum numbers same among the four quantum numbers.
Hence, the given statement is true.
No two electrons in an atom can have same set of four quantum numbers.
Pauli's exclusion principle: No two elwctrons in an atom can have the same values of all the four quantum number.
What is the maximum number of electrons in an atom that can have the quantum no.
