# orbital diagram of Iron, particularly the d orbitals

Hi!

I have to write the orbital diagram of the last sublevel in iron. Uh, i know that there are 5 types of d level orbital, but I don't know how I choose one of them. And could you please explain what teh

d_{yz}, d_{xz}, d_{xy}, d_{x2-y2}, and d_{z2} means?

Thank you

Otis

## Re: orbital diagram of Iron

d

_{yz}, d_{xz}, d_{xy}, d_{x2-y2}, and d_{z2}are mathematical derived names for the 5 d orbital orientations with respect to the x, y, and z axis. I've heard them called the 4 double dumbbells plus Homer (a giant dumbbell with a doughnut).The last level would look something like this

4s 3d

?? ?? ? ? ? ?

Remember Hund's Rule, no doubling until each each orbital of a sub-level has one electron.

Hope this helps.
