In this exercise, we have the bromine in the ground state.
00:04
The bromine has an atomic number of 35, and we have to find what is the maximum value for the angular momentum of an outer electron, for the bromine that is, an electron that is in the outermost shell.
00:23
So the first thing we need to do is to find the ground state electronic configuration of the bromine.
00:27
So here on the left, i have written the order according to which we should allocate electrons to the subshells of atoms.
00:39
So let's do that for the bromine.
00:41
We start by the 1s that fits two electrons, then 2s and 2p.
00:48
So up to now i have 10 electrons that are 25 to go.
00:53
The next sub -shell is the 2s, then the next is the 3p, and the next one is the 4 .5 .1.
00:59
4 s that fits 2 electrons, so we have 20 electrons up to now...
