Question

Assertion :According to Rutheford's atomic model, electron should fall into the nucleus Reason: Electron is a charged particle and it emits radiation while in motion and lose energy

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

The Rutherford's model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. According to the model 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.
