As an electron makes a transition from an excited state to the ground state of a hydrogen like atom/ion. |

Answer» its kinetic energy increases but potential and total energy DECREASES `:.` Potential energy in `n^(th)` orbit. `P.E=-(27.2)/(n^(2))eV` Kinetic energy `KE=+(13.6)/(n^(2))eV` and total energy `E=-(13.6)/(n^(2))eV` Hence, electron transist in ground STATE (n = 1), the value of n decreases hence value of PE. decreases (It is negative). Since kinetic energy increases but potential and total energy decreases (it is negative). |
