Q.

Which one of the following about an electron occupying the 1s orbital in a hydrogen atom is incorrect? (The Bohr radius is represented by a0)

  1. A

    The probability density of finding the electron is maximum at the nucleus

  2. B

    The electron can be found at a distance 2a0 from the nucleus

  3. C

    The magnitude of the potential energy is double that of its kinetic energy on an average

  4. D

    The total energy of the electron is maximum when it is at a distance a0 from the nucleus

Solution

The total energy of the electron is minimum when it is at a distance a0 from the nucleus for 1 s orbital.
