In a hydrogen atom the effect on potential energy of the electron with increase in radius of orbits will be: |
potential energy remains the same potential energy increases potential energy decreases potential energy initially decreases then increases |
potential energy increases |
Potential Energy is inversely proportional to radius but due to negative sign, when the radius is increased, the potential energy is also increased. Hence, when a hydrogen atom is raised from ground state to excited state, its potential energy increases whereas kinetic energy decreases. |
