In this question, we're given that a possible excited state for the hydrogen atom lies in the 5d orbital, and we're asked to list all sets of n, l, and m subl for this electron.
00:22
So let's go ahead and first define these.
00:28
N is the principal quantum number and tells us the energy level that the electron is at.
00:37
And this can range from one to any number, but it must be an integer.
00:45
L tells us the type of orbital.
00:51
And it ranges from 0 to n minus 1.
00:59
M subl, lastly, tells us the orientation of the orbital, and it ranges from negative l to positive l.
01:11
So let's go ahead and pick this apart.
01:14
We know it's in the 5d orbital, so we can immediately tell that n is going to equal 5...
