ml

Postby Maria Solis Disc 1G » Sun Oct 21, 2018 8:24 pm

On Friday's lecture Dr. Lavelle kept mentiong ml, can someone please explain what that is, as I am majorly lost. Also instead of doing a lowercase l can i use a cursive l, since one of the reasons i got lost was because i kept confusing the l with a 1.

I am pretty sure you can use a lowercase l. I do that as well because it can be quite confusing. I'm not exactly sure how to explain what ml is but from what I understand, it just tells you the subshell's (which is determined by l) orbitals orientation. So in the example he gave us, if the subshell is in the p orbital, then ml can be px, py, or pz.

ml is the magnetic quantum number. It serves to distinguish the individual orbitals in a sub shell (l). ml can take the values from -l to l. So if l = 1, ml = -1, 0, or 1. l = 1 signifies the p-orbital, so these 3 numbers can also be written as px, py, and pz. This means that there are three orbitals in a p sub shell which can hold a total of 6 electrons.

I also have this problem with the different v's that all have different meanings. Is there any way you write yours so you don't mess up?

You can definitely use a cursive l, that's what I use because I too confuse it with a 1. But for ml it determines the number of orbitals and the orientation within a subshell. Ml is dependent on l. So for example if l=2, ml would be -2,-1,0,1,2. I don't know if this is any help.

For the "v" for frequency (actually greek letter nu) my TA wrote it with a line over the top in his calculations and ever since I started doing that it's been a lot less confusing!
