Question

write the formula to calculate azimuthal quantum number​

Answer 1

Answer:

Azimuthal quantum number is a quantum number denoted by the letter

"l".

It is written after Principle quantum number.

It helps to understand the shape and number of orbitals in a shell ( orbit).

The best way to calculate Azimuthal quantum number is as follows :

1st case : IF PRINCIPLE QUANTUM NUMBER IS PROVIDED, THEN :

let principle quantum number be n.

then azimuthal quantum number

l =( n - 1)

2nd case : IF MAGNETIC QUANTUM NUMBER IS PROVIDED THEN:

let magnetic quantum number range from (-m) to (+m), then azimuthal quantum number

"l" will be numerically equal to "m".

Answer 2

Each distinct n, ℓ, mℓ orbital can be occupied by two electrons with opposing spins (given by the quantum number ms = ±½), giving 2(2ℓ + 1) electrons overall.
