<b> Sublevels are s,p,d,f etc. There are 1,3,5,7 orbitals in each and when each is filled can hold 2,6,10,14 electrons</b>

<b> I think this problem can be misinterpreted quite easily and I could make a case for either answer being correct. Initially I agreed with you; however, on re-reading about "diagnostic of the chemical composition of that SUBSTANCE". I am convinced the answer is false. For example, if I subject Na2SO4 to spectroscopic analysis, I can easily tell you Na ions are there BUT I can't tell you the identity of the anion. On the other side of the coin, if I can hand pick the compound AND the method, I might use infrared (same principles) and I could distinguish, for example, between Na2SO4 and KCl; therefore, under some conditions this could be a true statement. I assume this is a lower level class so I would go with false</b>
