Question

what is defects in Rutherford atomic model​

Answer 1

Answer:

There were two fundamental defects in Rutherford's atomic model: According to classical electromagnetic theory, being a charge particle electron when accelerated must emit energy. We know that the motion of electron around the nucleus is an accelerated motion, therefore, it must radiate energy.

Answer 2

Answer:

There was two fundamental defects in Rutherford atomic model : according to classical atomic theory. Being a charge particle when accelerated must emit energy. We know that the motion of electron around the nucleus are accelerated motion. Therefore it must radiate energy. But actual practice it does not happens.

continuous loss of energy orbit of electron must decrease continuously. Consequently electron will fall into the nucleus. But this is against the actual situation and this shows that atom is unstable.

If the electrons emit energy continuously, they should form continuous spectrum .But actually line spectrum is obtained.
