Document Summary
Exciting the electron: absorbs energy, jumps up a level. Change in color shows electron jumping: color corresponds to certain energy level. Excited state: anytime an electron is higher than the ground state: energy involved from one level to another. Heisenberg: product of uncertainty in position ( ), uncertainty in momentum(m v), can be no smaller than h/4pi; hgh uncertainty prevent us from defining exact moments. Schrodinger: wave and particle nature could be incorporated into math treatment. Quantum mechanics: mathematically describes particles; probability of finding a particle in a defined space is: probability= probability density *volume. Atomic orbital: wave function for electron; high probability of finding an electron.
