Question

Calculate for a hydrogen atom and a He ⁺ ion:

(a) the radius of the first Bohr orbit and the velocity of an electron moving along it;

(b) the kinetic energy and the binding energy of an electron in the ground state;

(c) the ionization potential, the first excitation potential and the wavelength of the resonance line (n' = 2→n = 1).

Answer 1

The basic equations have been derived in the problem (6.20). We rewrite them here and determine the the required values
