Question

Failure of Rutherford Theory? ​

Answer 1

Answer:

$\huge\pink{Answer}$

Explanation:

Drawbacks of Rutherford's model of atom. Rutherford proposed that electrons revolve at a high speed in circular orbits around the positively charged nucleus. ... Failure of Rutherford's model i.e. reduction of radius of orbit is shown below. Rutherford proposed that electrons revolve around the nucleus in the fixed orbits.

Answer 2

$\huge\purple{Answer}$

• Rutherford proposed that the electrons revolve around the nucleus in fixed paths called orbits. According to Maxwell, accelerated charged particles emit electromagnetic radiations and hence an electron revolving around the nucleus should emit electromagnetic radiation. This radiation would carry energy from the motion of the electron which would come at the cost of shrinking of orbits. Ultimately the electrons would collapse in the nucleus. Calculations have shown that as per Rutherford model an electron would collapse in the nucleus in less than 10-8 seconds. So Rutherford model was not in accordance with Maxwell’s theory and could not explain the stability of an atom.
• One of the drawbacks of the Rutherford model was also that he did not say anything about the arrangement of electrons in an atom which made his theory incomplete.
• Although the early atomic models were inaccurate and failed to explain certain experimental results, they were the base for future developments in the world of quantum mechanics.
