Document Summary

Frequency (v) number of times a wave repeats itself in a given amount of time, measured in hertz (hz) Wavelength ( ) the distance from one peak to the next, measured in nanometres (nm), 1nm = 10-9m. Shorter wavelength = higher energy and higher frequency. Longer wavelength = lower energy and low frequency. Bohr model each orbit is quantized (has a certain quantity of energy) considered electrons as a particle, but it only worked for the emission of hydrogen. Didn"t explain the splitting or intensities of emission lines. Particle-wave duality electrons can behave like waves and particles. Nodes where the wave has zero amplitude and there are no electrons in this area. Principal quantum number (n) indicates the energy level (n = 1, 2, 3 etc. ) Magnetic quantum number (ml) indicates the orientation of the orbital (ml = 0 to +/- l) Spin quantum number (ms) indicates the spin of an electron in an orbital (ms = +/- )
