- mathematical description of the quantum state of an isolated quantum system
- contains all the information about a particle
- no direct physical meaning
- extract information using operators or the born interpretation
- solving the schrodinger equation to get wavefunction

higher principle quantum number means higher energy
higher nuclear charge means lower energy
assume there is a free particle with v=0 on an axis going from
energy is kinetic only
