Question
When a hydrogen atom is raised from the ground state to an excited state
- P.E. increases and K.E. decreases
- P.E. decreases and K.E. increases
- Both kinetic energy and potential energy increase
- Both K.E. and P.E. decrease
The correct answer is: P.E. increases and K.E. decreases
As r increases K.E. decreases but P.E. increases
