Solution

The correct option is A TT
  • If the electrons lose energy continuously, the observed spectrum should be continuous but the actual observed spectrum consists of well defined lines of definite frequencies.
    Hence, the loss of energy by the electrons is not continuous in an atom.
  • Since, the nucleus of the atom is quite stable, it means the electrons do not fall into the nucleus. Therefore, Rutherford's model does not explain the stability of the atom.
