Focus 1: wave properties, e = h , c = i. ii. iii. i. De broglie"s equation - relates wavelength and velocity of particle c: particle in a 1d box a. i. = energy of particle: e n , n = principal quantum number, h = planck"s constant, m = mass of particle, l = length of box, what does the equation mean, quantum numbers a. 1, 2, 3, 4, 5, 6, 7 n-1 up to a. + or - b: how to tell what orbital it is based on the quantum number. Tells whether it is the up spin electron or the down spin electron: m l , m s n.
