If the electron in a hydrogen atom moves from ground state orbit to 5^ th orbit, then the potential energy of the electron

Options

  1. Ais increased
  2. Bis zero
  3. Cis decreased
  4. Dremains unchanged

Correct answer

A. is increased

Step-by-step solution

The potential energy of electron in hydrogen atom is given by U =- 1 4 ₀ e ^2 r Hence as r increase, potential energy will increase. (It will become less negative)
