Question

Urgently needed please give the answers !!!!!!!!!!

Answer 1

Rutherford's model of atom drawbacks:

Rutherford compared nucleus with the sun and electrons with the planets .as electrons undergoes acceleration while revolving around the nucleus . so as electrons are charged particles so it will emit electromagnetic radiation (according to Maxwell when charged particles accelerate it emits electromagnetic radiation).

(This feature does not exist for planets since they are uncharged)

Now, therefore an electron in an orbit will emit radiation,the energy carried by radiation comes from electronic motion.

The orbit will thus continue to shrink . But this does not happens actually. So this was the one reason of Rutherford's models drawback

Another serious drawback of Rutherford model is that it says nothing about distribution of the electrons around nucleus and energies of these electrons

Answer 2

Heya....

• The Rutherford atomic model was correct in that the atom is mostly empty space. Most of the mass is in the nucleus, and the nucleus is positively charged. Far from the nucleus are the negatively charged electrons. But the Rutherford atomic model used classical physics and not quantum mechanics.
