Question

Explain the drawbacks of Rutherford's model of atom

Answer 1

The major drawbacks of Rutherford's model of atom ----

1) Any charged particle when accelerated is expected to radiate energy. To remain in a circular orbit, the electron would need to undergo acceleration.
The revolving electron would lose energy and finally fall into nucleus. If this were so, the atom would highly be unstable. Therefore matter would not exist, but we know matter exists. Hence atoms are stable.

2) Rutherford could not explain the distribution of electrons in the extra nuclear portion of the atom.

Answer 2

Any particle in circular orbit would undergo acceleration
During acceleration , the positively charged particles radiate energy.
Thus , the e - would lose energy and fall into the nucleus.
If this would happen, the atom would become highly unstable and hence matter would not exist
