Multielectron vs H-atom

Postby JTieu_1L » Mon Nov 02, 2020 10:33 am

Which of the following increase when an electron in a lithium atom undergoes a transition from the 1s-orbital to a 2p-orbital? (a) Energy of the electron. (b) Value of n. (c) Value of l. (d) Radius of the atom. Which answers would be different for a hydrogen atom and in what way would they be different?

Does anyone know the answer to the second question? It does not say in the textbook solutions. Would c be the only one that is different?

So actually these are all the same as the hydrogen atom. All of these would increase so there is no difference to the hydrogen atom.

As Kareena said above I would think that these would all be the same for hydrogen as everything would increase for both the lithium and hydrogen. The energy would increase because it is going to a higher energy level. N would increase for the same reason. l would increase due to a change from s to p orbital and the radius would be larger because there would be more electron-electron repulsion. Hope this helps!

I believe that they all increase even for a H atom because when the energy level increases, so does the possible values for the quantum numbers.

So does that mean that even though the electron configuration for hydrogen is 1s1 (n=1, l=0, ml=0, ms=+1/2), the electron is not restricted to those quantum numbers and can potentially occupy n=2,3,4 shells and other sublevels?
Is the electron configuration for hydrogen 1s1 simply because that is its lowest energy state and therefore the most stable state?
