Homework Statement
Calculate the energy and radius for each of the five lowest (n = 1,2,3,4,5) electron orbits in a Helium atom with only one electron. Enter the energy as a positive value in units of "eV" and the radius in units of "nm". Hint: The Helium nucleus has 2 protons so Z = 2 and the ground state energy of Helium will be E0 = k(Ze)2/2r0.
Homework Equations
E = (E0/n2)*Z2
E0= 13.6 eV
Z2=4
r=(r0/Z)*n2
Z=2
The Attempt at a Solution
I got the correct answers for n = 1-2 and 4-5, but I cannot get the right answer for n=3. could you check my work?
The answers I got were E = 6.044 eV and r = .238 nm
