Question

stat and explain paulis exclusion principle​

Answer 1

Explanation:

pauils exclusion principle states that no two electrons in the same time atom can have identical value for all four of their Quantum numbers in other words (1) no more then two electrons can occupy the same orbital and (2) two electrons in the same Orbit must have opposite spins .

Answer 2

Answer:

No two electrons in an atom can have the same set of four quantum number's.

Explanation:

No two electrons can have four types of same quantum number's in an orbital.

Ex = 5S^2

= there are 2 electrons

n = 5

For 1st electron n=5 l=0 m=0 s=1/2.

For 2nd electron n=5 l=0 m=0 s= -1/2.

both electrons equal in n , m, l

but both are different in s.
