JEE Main 2019 Chemistry question

Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect? (The Bohr radius is represented by ).

(A)The magnitude of the potential energy is double that of its kinetic energy on an average.
(B)The probability density of finding the electron is maximum at the nucleus.
(C)The total energy of the electron is maximum when it is at a distance from the nucleus.Correct
(D)The electron can be found at a distance from the nucleus.

Answer: (C)

Solution

The total energy of the 1s electron is fixed; it does not depend on its instantaneous distance.
