Question

The sumof azimuthal quantum number of the orbital whose electron cause maximum screening and the

one whose cause minimum screening (for same value of 'n') is equal to​

Answer 1

Explanation:

mn causes minimum screening

Answer 2

Answer:

Shell no. of penultimate shell.

Explanation:

maximum screening is of s shell and minimum is of outermost shell

l of 1s = n-1 = 0

l of n(outermost) = n-1

sum of both = n-1

Penultimate shell - Penultimate shell is the electron-containing shell that is inner to the outermost valence shell

so penultimate shell = n-1
