Question

Give any two drawbacks of Rutherford’s model of atom

Answer 1

Answer:

✓✓™®©Drawbacks of Rutherford's

model of atom.

☑️Rutherford proposed that electrons revolve at a high speed in circular orbits around the positively charged nucleus. When a charged particle i. e. electron revolves around positively charge nucleus, it needs to be accelerated so as to keep it moving in circular orbits......

☑️The main problem with Rutherford's model was that he could not explain why negatively charged electrons remain in orbit, when they should instantly fall into the positively charged nucleus. This problem would be solved by Danish physicist Niels Bohr in 1913......

Answer 2

Answer:

• Rutherford proposed that electrons revolve at a  high speed in circular orbits around the positively  charged nucleus. When a charged particle i.e.,  electron revolves around a positively charge  nucleus, it needs to be accelerated so as to keep  it moving in circular orbits. However, according  to electromagnetic theory, whenever a charged  particle such as an electron is accelerated around  another charged center (nucleus) which is under  force of attraction, there will be continuous  radiation of energy. This loss of energy would slow  down the speed of the electron. This would reduce  the radius of the electron orbit. Eventually, the  electron would fall into the nucleus. The result  would be that the atom would collapse. But this  does not happen.
• Thus, Rutherford’s atom could  not explain the stability of the atom. Failure of  Rutherford’s model i.e., reduction of radius of  orbit . Rutherford proposed that  electrons revolve around the nucleus in the fixed  orbits. However, he did not specify the orbits and  the number of electrons in each orbit.
