Answer 1

Hey dearie.....^_^

Here's ur ans.⤵

Hund's Rule of Maximum Multiciplity ⬇

According to this rule pairing of electrons in an atom (2 or more than it) will not take place until all the orbitals are singly occupied or half filled .

Spin Multiciplity = 2|s| + 1

where s = Multiciplity
n = no. of unpaired electrons

Then spin of electrons must be parallel.

✌Hope it helps sisy ☺

Answer 2

Hund's rule of maximum multiplicity states that the electrons arrange themselves in degenerate orbitals in such a way that their spin multiplicity is maximum. Spin multiplicity is given by 2s+1 where s is the the total spin of electrons.

To put it simply no pairing of electrons will start in any degenerate orbitals untill all of them have one electrons each with parallel spin.

This is because electrons can have two spin states up and down which are represented by numbers +1/2 and -1/2. Maximum multiplicity will only be achieved if all the electron are of +1/2 spin. And in any orbital only two electrons can be accomodated with opposite spins. So one electron with spin+1/2 will go in all orbitals and then only pairing will start as this will reduce spin multiplicity because now -1/2 spin electron will be added in the orbital.

Hope you understand it and mark as brainliest thanks.
