Identifying orbitals via quantum numbers
« on: October 16, 2009, 08:48:17 PM »
For each pair of quantum numbers, give the name of the orbital they describe (1s, 4d, etc.):
(a) n = 3, l = 2
(b) n = 6, l = 1
(c) n = 5, l = 0


Here are my answers:
(a) 3p orbitals
(b) 6s
(c) 3s

n=principal quantum number. This signifies the main shell number

l=azimuthal quantum number. This signifies the subshell(s,p,d,f)

@UG: I know s,p,d,f exist. Is there any atom whose electrons occupy g/h levels?

The only atoms whose electrons would occupy g/h levels are, in my experience, atoms that have undergone electron excitation, i.e., atoms that are in their 'excited states'. I don't think any atoms at ground level do.

I was about to suggest the same thing as mizzle (welcome by the way), at their ground state I would think not.
But they've got shapes   :)  http://www.d.umn.edu/~pkiprof/ChemWebV2/AOs/ao5.html

how come there are only 4 g orbitals?

I have updated my knowledge of quantum mechanics and now here are my answers:

(a) 3d
(b) 6p
(c) 5s

Correct technique? :P

Yes, Correct.
