2n square

It is used in ARRANGMENT OF ELECTRIC CONFIGURATION of electron

• THE MAXIMUM NUMBER OF ELECTRONS IN ANY ENERGY LEVEL OF THE ATOM IS GIVEN BY 2nSQURAE.

FOR EXAMPLE.

we know that in 1st shell 2 ELECTRONS come

in 2d shell 8 and so on..

but if we forget it or we need to take out big shells so:

suppose i need to take out 1st shell:

2nsquare= 2×1×1=2 so the no. of electrons in first shell will be two

(n=which shell /no. of shell)

now for 3rd shell

2nsquare= 2×3×3=18

so the no. of electrons in the third shell will be eighteen.
