| Term | Definition |
|---|---|
| DeBrogile | electrons have wave like properties, they can be diffracted and can interfere with on another |
| Heisenberg | there is uncertainty when finding an electron, you don't know where an electron is at a certain time but you know with about 90% probability |
| Schrodinger | equation to treat electrons as wave- the solution to this equation is around where the electron is there are no rings there are three dimensional areas where the electron is |
| Principal quantum number | (n) indicates the main energy level |
| Angular momentum quantum number | (l cursive) indicates the shape of the orbital (spdf) |
| Magnetic quantum number | (m) indicates the the orientation of an orbital around the nucleus l |
| spin quantum number | (m ) 2 possible values that represent the spin state counter/clock s |
| Aufbau Principle | electrons are found at the lowest energy levels before they are found are higher levels |
| Pauli exclusion principle | when electrons occupy the same orbitals they must have opposite spins |
| Hund's rule | for orbitals of equal energy each orbital must have one electron before it would have a second |
