Help with MO diagrams. Next examples and explanation (antibodies, pi bonds, sigma)etc

Vocaloid:

ehh I was never really the greatest @ these but what are your questions?

zarkam21:

Like when you start filling them where you start etc etc

zarkam21:

just the basic

zarkam21:

how i detemine the anotibonding

Vocaloid:

uh well usually you just add up the valence electrons of the two atoms involved, then fill up from the bottom according to hund's/afbau/etc.

Vocaloid:

like for this one, sulfur has 6 valence electrons so you'd fill up 6 on each side (green) then fill up 12 electrons in the middle (purple)

Vocaloid:

anything starred* is antibonding; if all the antibonding orbitals are filled up that means the molecule is very unstable and probably doesn't exist to any appreciable extent in real life which is why He2 isn't a thing but H2 is

Vocaloid:

idk i feel like it's easier to just start with a HW question instead of starting from scratch b/c there's a lot of theory involved in this

zarkam21:

Ugh I know your not on right now. I ended up falling asleep
