Question

Why are half- Filled and completely filled orbitals More stable


Explain with 2- example?


❌❌No spam❌❌

Answer 1

Answer:

The reason for their stability are symmetry and exchange energy. The half-filled and fully-filled orbitals are more symmetrical than any other configuration and symmetry leads to greater stability. The electrons present in the different orbitals of the same sub-shell can exchange their positions.

Answer 2

$\huge\underline\red{\sf Answer}$

Stability of half filled and full filled orbitals :

➡ The half filled and full filled orbitals are more stable.

➡As they are more symmetrical compared to other configuration.

➡The symmetry leads to more stability .

➡electrons present in different orbitals of the same sub-shells can exchange their position..

➡example nitrogen.

it's e.c is 1S2 2S2 2P3

here p orbital is half filled.

➡example neon.

it's e.c is 1S2 2S2 2p6

here p orbital is full filled.
