1. The problem statement, all variables and given/known data (a)the electric potential established by the nucleus of a hydrogen atom at the average distance of the circulating electron (r = 5.29 multiplied by 10-11 m) I solved this part using V = kq/r and got 27.2249V (b) the electric potential energy of the atom when the electron is at this radius, and I thought this was a simple as converting to electron volts but it's not? What is next? This is where I am stuck. (c)the kinetic energy of the electron, assuming it to be moving in a circular orbit of this radius centered on the nucleus. (d) How much energy is required to ionize the hydrogen atom (that is, to remove the electron from the nucleus so that the separation is effectively infinite)?
