Question

What is the third quantum number of a 3s² electron in phosphorus,

1s²2s²2p 3s²3p³?
A. m₁ = 3
B. m₁ = 2
C. m₁ = 0
D. m, = 1

Answer 1

The third quantum number of a 3s² electron in phosphorus is m₁ = 0. The electron configuration of phosphorus is [Ne]3s²3p³. The outermost shell is the third shell, so here, n = 3.

I hope this helps!
