Is there a different name for orbitals with both n=x, l=1+but ml is different?

[JustinCh3m]

Hi, can you clarify?  Do you mean for any integer "n,"  ->   l = {0, 1,...(n-1)}, ml = {-l,...0,...+l}  ??

If you expand on your question I may be able to help...

[Boxxxed]

lets say for

n=3, l=2, ml=0

n=3, l=2, ml=1

Are they both 3d? or does the ml have any effect

[Schrödinger]

m_l does matter. Both are 3d orbitals, but are not oriented in space in the same way... There are five 3d orbitals with m_l ranging from -2 to +2. They are named 3d_z², 3d_x²-y², 3d_xy, 3d_yz and 3d_zx

[Boxxxed]

So how do I know which ml value applies to which orbital name?

[JustinCh3m]

of the 5 d-orbitals, the ml values would be as such:

_    _   _  _  _
-2  -1  0  1  2

with each ml representing a different orientation

[Boxxxed]

I realize that there are five ml values representing the five 3d orbitals. But do the specific values themselves attribute themselves to a particular orbital? Does ml=-1 attribute itself to 3dz2 etc.

The values of magnetic quantum number do correspond to specific orbitals.
m_l=0 => d_z²
m_l=+1 => d_xz
m_l=-1 => d_yz
m_l=+2 => d_x²-y²
m_l=-2 => d_xy

[Boxxxed]

How is that derived? I've read the whole chapter and my book doesn't say how to name it past the 'l' value.

[Cherriyan]

That's based on complex quantum mechanical calculations which haven't been taught to me till now!
