Question

If a proton had a radius R and the charge was uniformly distributed, calculate using Bohr theory, the ground state energy of an H-atom when R=10 Armstrong

Answer 1

put the value and find it by this formula

Answer 2

radius of atom => R =0.0529*n^2/z

and

Energy = 13.6*z^2/n^2

dividing both the eqns. we get,

r/E = 0.0529/13.6z

E = r*13.6*z/0.0529 => 10*10^-10*13.6*1/0.0529 => 2.57 * 10^-7 J
