2.1 help

Postby Amanda Cardenas 1J » Thu Apr 26, 2018 7:35 pm

2.1: Which of the following increase when the electron in a hydrogen 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

They all increase because for the 1s orbital: n=1 and l=0, and for the 2p orbital: n=2 and l=1. Therefore, both n and l increase. Also, the energy of the electron increased because the electron jumped to a higher energy level. The radius of the atom also increases because the 2p orbital is further from the nucleus than the 1s orbital.

Hello Amanda,
Susu is right, they all increase. When an electron jumps orbitals, like from s to p, the energy is increasing. This would make a yes. When this electron makes this jump, the electron goes from originally having values of n=1 and l=0 to n=2 and l=1, so this makes b and c yes. Lastly, because the nucleus is the center of the orbit that this electron is making and the 2p orbital is further than the 1s orbital, the radius would increase.

It was my understanding that each shell has at least 1 subshell: s,p,d, or f. Therefore, if an electron changes subshells, is it possible for it to remain in the same shell? If so, then wouldn't electrons in the same shell have the same value for "n"?
