Question

The azimuthal quantum number for 17 electron of cl atom is

Answer 1

Answer:

n = 3

l = 1 (p)

m = -1 \ 0 \ 1  (can be any of them)

s = +1/2  or   -1/2    (can be any of them)

Explanation:

electron configuration is:

1s², 2s², 2p⁶, 3s², 3p⁵(test electron in the last one)

∴

n = 3

l = 1 (p)

m = -1 \ 0 \ 1  (can be any of them)

s = +1/2  or   -1/2    (can be any of them)

Answer 2

Electronic configuration of chlorine atom is 1s2 2s2 2p6 3s2 3p5

The last electron is in M-orbit

Which means n=3

Then l=1 because it is in the P-orbital..

Hope this helps..........
