What do the four quantum numbers stand for?
1 Answer
Principal quantum number (
Angular momentum quantum number (
If
#ℓ=0# it is the s-orbital, if it is 1 then it is the p-orbital, 2 means d-orbital, etc. This number is often pair with n, so that if#n=4, and ℓ=2# , it is in the 4d subshell.
Magnetic quantum number (
There are
#2l+1# orbitals per subshell. This is proven as if#ℓ=1# , then#2(1)+1=3# , there are three orbitals for the p subshell. If#ℓ=2# , then#m_ℓ =-2, -1, 0, 1, 2# , 5 orbitals for d-subshells.
Spin quantum number (
