Bohr radius of a helium ion

[QUOTE="leroyjenkens, post: 4527359, member: 162373"] [h2]Homework Statement [/h2] Using the Bohr model, find the atomic radius for a singly ionized He+ atom in the n = 1 (ground) state and the n = 2 (first excited) state. Then find the wavelength of the emitted photon when an electron transitions from the n = 2 to the n = 1 state.[h2]Homework Equations[/h2] [tex]a_0 = \frac{4∏e_0h^2}{me^2}[/tex] m = mass of the electron h = h bar. Reduced Planck's constant e = elementary charge[h2]The Attempt at a Solution[/h2] I need some way of adding a proton and a neutron to the equation, but there's no such variable. I can't find any equation relating to the Bohr radius that isn't just constants. The Borh model can supposedly give you the radius of a helium cation, but that's the only equation I can find and it's all constants. [/QUOTE]
