Chapter 7 review λ : Wave length ( meter) ν : Frequency ( Hz = s -1 ) h : = 6.626* 10 -3 (J.s) Planck’s constant c: 3.00 *10 8 (m/s) speed if light E: energy of photon E= hc/ λ E= h ν νλ = c (Wave length and frequency are inversely proportional) Wave length : distance between 2 corresponding points on the wave Frequency : a measure of the # of wave cycles that move trough a point in space in 1 second.-> Characterize Electromagnetic radiation When a electron moves from a higher energy orbit to one that’s lower in energy -> e - release an amount of energy Δ E= E final - E initail (p. 246) Bohr “Orbits” actual paths of electrons movement 2D, fixed distance energy levels quantized as the level go higher, distance between levels closer Modern “Orbital” 3D region in space where the highest probability of finding an electron is. Energy levels are still quantized ( have only certain energy) Why cant we say exactly where the electron is? Because it’s moving and really tiny
