Document Summary

Na = 6. 022 x 1023 mol-1 c = 3. 00 x 108 m/s h = 6. 626 x 10-34 js me = 9. 11 x 10-31 kg e = 1. 602 x 10-19 c. E = h hc h = h o + ke. 2 n2 energy difference between energy levels n1 and n2 for h atom. B: the ionization energy for the h atom is the energy difference bwteen n=1 to n= . Using the energy equition for h atom, the ionization energy for h is determined to be (in j): 1: 4. 36x10-18; b) 2. 18x10-18; c) 1. 09x10-18; d) 2. 18x10-19; e) none of the above. B: based on coulomb"s law, when the na+ and cl- ions are placed 10 nm apart, their interaction energy should be, 2. 31x10-19 j; b) -2. 31x10-20 j; c) 2. 31x10-20 j; d) -2. 31x10-19 j; e) -2. 31x10-18. B: for a particle with mass m in a one dimensional box of lenth l, the energy is given by:
