Can someone please explain the difference between Px, Py, and Pz? Thank you!

They describe the locations of electrons in a P-orbital. So instead of saying "these electron are in the front and back," we can say "their positions are on the x-axis"
since they are in P-orbital, we state their location as "Px"

same idea for Py and Pz

Do you know how from n=2, l=1, m=-1 we could now it's e- in 2Px state?

I get the 2 and the P. But I don't know how to decide it's Px.

Thanks.

In my opinion, the positioning depends on how you decide to place the 3D Cartesian axis, so it's arbitrary. In the d-block, there are Dxy, Dxz, etc
I think they assign the coordinates is to give people a better understanding of where an electron locates relatively to other electrons graphically.
