Question

Explain, in brief, why Rutherford’s model cannot account for the stability of an atom?

Answer 1

According to Rutherford's model of anatom, electrons revolved around the positively charged nucleus. But, due to this the electrons will accelerate and radiate energy. The electrons will finally fall into the nucleus. Thus, theatom will become highly unstable.

Answer 2

Answer:

Rutherford’s model cannot account for the stability of an atom because the electron’s speed will keep reducing as the electron keeps giving off energy by emitting radiation and the radius of its rotation will keep decreasing and it will soon crash into the nucleus which does not happen.

Explanation:

The Rutherford model cannot account for the stability of an atom due to the following reasons:-

• An accelerating charged particle must emit electromagnetic radiation, according to electromagnetic theory.
• An electron spinning around the nucleus accelerates towards the nucleus' core.
• The atom, according to Rutherford's model, is made up of a compact, dense, positively charged core called a nucleus, in which nearly all of the mass is concentrated, and around which the light, negative parts, termed electrons, circulate at a distance, much like planets rotating around the Sun. According to the model, the electron's speed will continue to decrease as it emits energy and the radius of its revolution will continue to shrink, and it will eventually smash into the nucleus, which does not occur.

Hence, we can conclude that Rutherford's atomic model could not explain the stability of the atom as a whole.
