Unformatted text preview: i. There is none. There must be energy lost for emission ii. absorption is required to go from lower to higher energy III. Atom & Probability A. 3D Probability density ψ 2 prob/m 3 1. Total Probability ψ 2 *ΔV 2. Prob{shell} = ψ 2 *(surface area)*(Δr) a. Small Δr = dr (then take integral) i. Prob = integral(ψ 2 *(surface area) dr) b. Example: total probability = 1 i. Since ψ is constant ψ 2 *ΔV = A 2 4/3 πr 2 = 1 1. A = sqrt(3/4πr 2 ) 2. Probability = integral of P(r)dr A = sqrt(3/4πr 2 ) IV. Fluorescence A. Illuminate with one color and emits at different colors 1. Photons jump several energy levels due to a high energy photon a. Smaller downward jumps lower energy photons Bohr Model for Hydrogen E n = 13.6eV/n 2 (ONLY FOR HYDROGEN) E ph = ΔE transition  3D Probability Distributions Radial probability distribution function P(r) = P r = 4πr 2 ψ 2...
