@50817bigb 3d comes after 4s. remember the list he did in the beginning with the diagonal arrows?

brooklyn college anyone?
-
why did you skip 3d in the calcium example?
-
how many boxes under d's?

@mysstring1 It's complicated is my best answer. Electrons in an atom are required to be in different states (these are what the quantum numbers means or describe) in the same way 2 people need to be in different seats. 2 people (or any object for that matter) cannot occupy the same space. Electrons of the same spin (a type of state) need to be in separate orientations so that gets filled first. Once they all have 1 electron, opposite spins (a different state) can can join them.

last question, when would we need to use boxes to draw electrons in and why are the electrons placed in opposite directions? does it suggest that in reality, electrons always spins in PAIRS and never collide?

@mysstring1 They never collide. They have the same charge & so repel each other. They aren't really spinning, they have properties of "spin". They need to be opp in an orientation or the atom could have overall angular momentum (meaning it could "roll away". Think about a bike with both wheels rolling the same way, it moves, if you could get them to spin in opp directions it would stay still. Atoms "stay still" so their electron spins need to be opposites. This is only an analogy)

what does it mean by s have 1 orientations and p has 2?
- what does quantum number mean in this orbital theory^^ thanks

@mysstring1 the quantum numbers represent the different states the electron can be in. They are a way of describing the electron since they don't have familiar qualities like "colour" or "size".

I don't get from going down the list you get 2p6 When carbon was 2p2
