Question

The ratio of energy of the electron in ground state of hydrogen atom to the electron in first emited state of be+3is

Answer 1

Answer:

The He+ ion is just like a hydrogen atom with two units of charge in the nucleus. Since the hydrogenic energy levels depend upon the square of the nuclear charge, the energy of the remaining helium electron should be just 4x(-13.6 eV) = -54.4 eV as observed.
