Homework Question 1E.1

[chrisavalos-2L]

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

- I think that the answer to this question is (d), because moving to this orbital would increase the size of the shel of the electron. I am not completely positive on this though if anyone could help me with the the explanation or to the right answer that would be very helpful. Thank You

When the electron undergoes the transition from 1s-orbital to a 2p-orbital all of the choices are correct. This is because, when it jumps to a higher value of n (n=2) it gains energy as the n increased from 1 to 2. Also, the value of l increases as the p subshell represents l = 1 while the s subshell represented l = 0. Finally, the radius increases as the electron is found further away from the nucleus of the atom.
