In a hydrogen atom, an electron is electrically bound to a proton. The binding energy is the energy required to pull the electron away from the proton. The binding energy depends on k = the Coulomb constant = 9 x 109 kg m3 s-2 C-2, h = Planck's constant = 6.6 x 10-34 kg m2 s-1, m = the mass of the electron = 9.1 x 10-31 kg, and e = the magnitude of the electron's charge = 1.6 x 10-19 C. There is only one way to combine k, h, m, and e in such a way that it has units of energy. That is, ?=???ℎ?????E=Akahbmced , where A is a dimensionless constant, and a, b, c, and d are various powers. Assuming A = 1, estimate E, in units of 10-19 J.
