Question

write a possible value of L when the principal quntum number is 3​

Answer 1

Answer:

Rules Governing the Allowed Combinations of Quantum Numbers

The angular quantum number (l) can be any integer between 0 and n - 1. If n = 3, for example, l can be either 0, 1, or 2. The magnetic quantum number (m) can be any integer between -l and +l.

$\sf\underline{Question:}$

Write possible values of l when the principal quantum number is 3

$\sf\underline{Answer:}$

Given, the principal quantum number is 3

The maximum value for l (azimuthal quantum no.) = n - 1

$l_{max} = n - 1$

$l = 3 - 1 = 2$

Max value of l = 2, 'l' can range from 0 to 2

When the value of principal quantum number is 3, possible values for l are 0, 1, 2
