Why are there no 2d orbitals?


Thanks

Dear cliverlong;

Because there are no 3f Orbitals, and no 1d O., and no …, and no .. !

Or a little simpler spoken: 
That’s the way how Mother Nature has organised, and the “Schrödinger Equation” seems to be an adequate model for it:

Sorry!, if that’s maybe too philosophic for you.
Good Luck!
