63. What work must be done to ionize a hydrogen atom, ie to remove an electron whose charge is e = –1.6 ∙ 10−19 C from a proton at a very large distance? The diameter of the hydrogen atom d should be taken equal to 1.0 × 10–8 cm. Express work on the ionization of the atom in electron volts (1 eV = 1.6 × 10–19 J).
