In Parts B and C you saw that, according to Bohr's postulate, the electron radius r and the electron velocity v only have certain allowable values. Plug the values obtained for these two quantities into the energy statement given below (E=) to arrive at a new statement for the allowed energy levels in the Bohr atom. Express answer in terms of e, m, n, h, \epsilon _{0} . Equations:

v=nh/2mr\pi

r=n^{2}h^{2}\epsilon _{0}/m\pi e^{2}

E=\frac{1}{2}mv^{2}-(e^{2}/4\pi r\epsilon _{0})
