Question

explain the rules for filling of orbitals in an atom
​

Answer 1

Answer:

Hund's rule states that orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron and that each of the single electrons must have the same spin. The Figure below shows how a set of three p orbitals is filled with one, two, three, and four electrons.

Answer 2

Explanation:

RULES FOR FILLING THE ORBITALS IN AN ATOM ARE :-

According to Bohr and Bury Scheme,..

1. The maximum number of electrons accommodated in a shell is given by the formula 2n^2, where n is the number of shell.

2. It can be filled as follows :-

K shell = 2 x 1^2 = 2 electrons

L shell = 2 x 2^2 = 8 electrons

M shell = 2 x 3 ^2 = 18 electrons

N shell = 2 x 4^2 = 32 electrons

3. The maximum number of electrons in an orbit is 8 electrons.

4. The orbits are filled in a step wise manner. Until and unless the smaller orbits are not filled, larger orbits cannot be filled too..

Hope it helps!
