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

Options

  1. AAssertion and Reasoning are correct statements and Reason is the correct explanation for Assertion
  2. BAssertion and Reasoning are correct statements and Reason is not the explanation for Assertion
  3. CAssertion is correct, Reason is wrong
  4. DAssertion is wrong, Reason is correct

Correct answer

D. Assertion is wrong, Reason is correct

Step-by-step 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).
