Question

the correct set of quantum numbers for the last electron of phosphorus atom is

Answer 1

Atomic number of Phosphorous = 15

Thus the electronic configuration of Phosphorous is - 1s2 2s2 2p6 3s2 3p3

So, the correct set of quantum numbers for the last electron would be -

-Principal quantum number 'N' = 3

-Angular momentum quantum number l =1

-Magnetic quantum number 'ml' = 2, 1, 0, -1, -2

-Electron Spin quantum number 'ms' = +1

Answer 2

Answer:

N=3 l=1 m=-1 s=+½
