or Chlorine fluroide which doesnt exsist to the best of my knowledge. I suppose if you can have a CL2 molecule you could be subsistuting one of the chlorines for a fluroine. What exam board and level is this for?
What exam board and level is this for?
yep, its degree level.... even if anyone knows any sites i can look at?
Which bit of it are you stuck on exactly? I'm not in chem mental mode at the moment so if you could spell out the question and the problem that'd help me think it through, and if I can help I will (although physical chemistry isn't my forte by a long road!!)
is that right?
Hmm. I have an orbital energies graph in front of me which helpfully doesn't show anything but fluorine 2s and 2p - however it looks to me like the fluorine 2p is highest in energy, followed by the 2s and then - at least this is implied by the graph - chlorine's 2p and 2s are considerably lower (off the scale on this graph which is why they're not shown). I think this does make sense if you think about it - chlorine is less electronegative overall but has a considerably higher nuclear charge than fluorine, so the electrons as close to the nucleus as 2s and 2p should be held more strongly and so at a lower energy than fluorine's. I think there's quite a gap though so I don't envy you for drawing the orbital diagram...!
- so yeah, exactly what you surmised.
Phew, sorry about that, must not be working on a full brain today!
.....and is the order of the atomic orbitals for Cl and I the same as Cl and F:
The graph only goes up to the 4th principal shell but it looks to me, from the patterns on here, as though your prediction may be right... But I really can't say for certain because the pattern isn't consistent so it's kinda hard to predict the shape of the 5s line. I think your suggestion's probably reasonable though. Sorry I can't be more helpful than that!
