Question

Mention one postulate about Rutherford's atomic
model which makes the atom highly unstable,​

Answer 1

Answer:

Rutherford postulated some characteristics of an atom ; one of them is as follows:

• The positive charge is located , concentrated on the centre.
• Electrons move in circular paths called orbits around the nucleus.

The 2nd postulate makes the atom extremely unstable because of the following reason:

1. According to Maxwell's Electromagnetic theory, if a charged particle os accelerated around another charged particles , it emits Energy.
2. Hence , as the electrons move around the positively charged nucleus, they are bound to lose energy and go into spiral circuit, finally falling into the nucleus.
3. This makes the atom extremely unstable.

Answer 2

if a charged particle os accelerated around another charged particles , it emits Energy. Hence , as the electrons move around the positively charged nucleus, they are bound to lose energy and go into spiral circuit, finally falling into the nucleus. This makes the atom extremely unstable.
