2.2.1 Shells and Orbitals
Shells
- 2n^2 to work out the maximum amount of electrons a shell can hold
Atomic Orbital
- a region of space that is likely to hold 2 electrons, with opposite spins
What shape is a s orbital?
- spherical
What shape is a p orbital?
- 3D dumbell shape
subshells fill up in this order
- 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d, 4f
How do orbitals fill up?
- lowest energy levels
- last in, first out
- filled singly before pairing
electrons have opposite spins
