Question

How to find electron spin quantum number?

Answer 1

the orbitals fill up with an electron spinning in the same direction until each orbital has one electron then start filling in with spin in opposite direction so if you fill the p orbitals you go up, up, up, dn, dn , dn when drawing the little arrows etc. this is+ 1/2,+ 1/2, + 1/2 as the 1st electron in px,py, and pz then you'd go -1/2 

so to answer your question __ p 1,2,3 are up or + 1/2 and __p4,5,6 are down or -1/2
