[[Wave Function]]
## Quantum Numbers
$$n$$
Principal quantum number
- 1, 2, 3...
- ***Electron shell***, electron energy and size of orbital
$$l$$
Orbital Angualar Momentum Number
- $0-(n-1)$
- ***Shape*** of the orbital
- 0 = s
- 1 = p
- 2 = d
$$m$$
Z-component / Magentic of $l$
- $-l$ to $+l$
- ***Orientation*** of orbital

## Filling
1. Aufbau
- Start lowest in energy
2. Pauli's Exclusion
- Max two electrons per orbital
- No two electrons can have same n, l, m, s tuple
3. Hund's Rule of Maximum Multiplicity
- Orbitals with same energy filled one at a time
- Degenerate

## Radial
![[radial-equations.png]]
- Z = Atomic number
- Bohr radius
- $a_0=\frac \hbar {\alpha mc}$
- Normalisation
- $\int_0^\infty r^2R_{nl}^*R_{nl}dr=1$
