Choose the correct option regarding: Assertion Energy of the orbital decreases with increase of ' \(n\) '. Reason Energy is required in shifting away the negatively charged electron from positively charged nucleus
  1. Assertion and Reasoning are correct statements and Reason is the correct explanation for Assertion
  2. Assertion and Reasoning are correct statements and Reason is not the explanation for Assertion
  3. Assertion is correct, Reason is wrong
  4. Assertion is wrong, Reason is correct

Solution

As we move away from the nucleus, in atom the potential energy of electron increases, as the distance for nucleus increases, the value of \(n\) increases. Consequently the kinetic energy of the electron decreases, but total energy as a whole increases. Thus, the Assertion is incorrect but Reason is correct. Hence, the correct option is (d).
