Magnetic Quantum number

Postby Gerald Bernal1I » Wed Oct 16, 2019 8:55 pm

Could someone explain how we are able to get 2,1,0,-1,-2 when we are finding the magnetic quantum numbers(ml) for the d orbitals. I know it goes l, l-1,..-l but how do we get -1 from this pattern? I am thinking 2,1,0(l-2), but would we get -1 from l-3 or something else? Could someone explain the pattern?

For ml, it takes all values from -l to +l or vice versa. L for the d-orbitals = 2, so the ml values for d-orbitals goes from -2, -1, 0, 1, 2.

The easiest way to make sure you got all the number is to make sure that their is a one value for the about of subshells present in the orbital (aka if you are dong the d orbital there should be 5 numbers: 2,1,0,-1,-2)

In the 3p subshell, where l=1, does this mean ml=0? Can ml=0?

Yes. The possible magnetic quantum numbers ml for electrons with l=1 (p-orbitals) are -1, 0, 1.
