Question

State and explain paoli exclusion principle and write the electronic configuration of element with atomic number 24

Answer 1

Answer:

Pauli's exclusion principle states that:-

The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously.

EXPLANATION:-

it means that no two electrons can occupy same quantum state in an atom. At least the values will differ in one of the 4 quantum numbers. That is no two electrons will have same PRINCIPLE, AZIMUTHAL ,MAGNETIC, SPIN quantum no. same , at least one will differ.

element with atomic no. 24 is chromium

electronic configuration:-

2,8,8,6

for higher level electronic configuration will be:-

1s2 2s2 2p6 3s2 3p6 4s2 3d4

hope it will help you mate .

thank you
