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 $a_0$)

• A. The electron can be found at a distance $2a_0$ from the nucleus
• B. The probability density of finding the electron is maximum at the nucleus.
• C. The magnitude of potential energy is double that of its kinetic energy on an average.
• D. The total energy of the electron is maximum when it is at a distance $a^0$ from the nucleus.

Answer 1

Answer: (D)

Correct answer is (d) The total energy of the electron is maximum when it is at a distance $a^0$ from the nucleus.
