Electron Configuration:

What numerical values of l are possible for n=4.

1,3,5,7

what ae their corresponding letters.

s,p,d,f

Are these correct?

No. "ell" can be 0,1,2,and 3 for n = 4.

s,p,d, and f are the correct names.

Yes, you are correct. For the electron configuration of an atom, the principal quantum number (n) determines the energy level or shell that an electron occupies. The azimuthal quantum number (l) specifies the subshell within a particular energy level where an electron is located.

For any given value of n, the allowed values of l range from 0 to (n-1).

In the case of n=4, the possible values of l would be 0, 1, 2, and 3.

The corresponding letters to these values are:

- l=0 corresponds to the subshell s
- l=1 corresponds to the subshell p
- l=2 corresponds to the subshell d
- l=3 corresponds to the subshell f

Therefore, you are correct that for n=4, the possible values of l are 0, 1, 2, and 3, and their corresponding letters are s, p, d, and f, respectively.
