Question

write two short comings of Rutherford model.

Answer 1

Hey,

SHORTCOMINGS OF RUTHERFORD MODEL:

1. According to electro-magnetic theory , an accelerated charged particle must radiate electromagnetic energy .

So , when an electron moves around the nucleus , it should radiate energy continuously and finally , should collapse in the nucleus .

But this doesn't happen . So , Rutherford's model wasn't able to explain the stability of an atom.

2. In Rutherford's model , an electron can revolve in orbits of all radii . So , it should emit contiguous spectrum . But an atom like hydrogen always emits a discrete line spectrum.

HOPE THIS HELPS YOU

HAVE A GREAT DAY
