I think I'm gonna get a tutor for this
Someone who can draw me diagrams and squiggles etc.
pretty much
also the lower energy electrons experience a lot greater nuclear attraction as they're closer to the nucleus, and electron shielding reduces the attractions to the outer electrons.

My college gave people free 1-to-1 tuition if they were struggling, maybe look into something like that? I tried it for maths and didn't find it particularly helpful but I know people who found it a lifesaver.

Religion is like a penis.
It's fine to have one.
It's fine to be proud of it.
But please don't whip it out in public and start waving it around.
And PLEASE don't try and shove it down my throat.
