Bohr's model of the atom assumed elec-
trons are in orbits of fixed radii. Which of the
following is/are a consequence of this assump-
tion?
I) The higher energy electrons are closest
to the nucleus.
II) The energy differences between orbits
correspond to energies observed in hy-
drogen emission line spectra.
III) The electron in hydrogen requires an in-
finite amount of energy to ionize.
