Question

Which of the following quantum number is different for the degenerate vacant atomic orbitals of an atom other than hydrogen?
a)principal quantum number
b)azimuthal quantum number
c)magnetic quantum number
d)spin quantum number
Answer required with proper explanation,

Answer 1

Spin quantum number

Explanation:

d) spin quantum number

principal quantum number is the principal  

Orbit no in which the electrons rotate and revolve

And they can be same for any atom .

Azimuthal quantum number defines  the angular

Momentum which also cam be same for any given  

Electron .

Magnetic quantum number defines the orbital is in

Which particular subshell that is s,p, or f which also  

Can he same for any given electron

Whereas spin quantum number defines the spin of

Electron in a subshell which is different for each and  

Every electron and for each atom .
