Practicing Success
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 |
P.E. increases and K.E. decreases |
P.E. $\propto-\frac{1}{r}$ and K.E. $\propto \frac{1}{r}$ As r increases so K.E. decreases but P.E. increases. |
