In Bohr's atomic model of hydrogen, let and are the kinetic energy, potential energy and total energy of the electron respectively. Choose the correct option when the electron undergoes transitions to a higher level :
Options
- AAll and increase.
- B decreases, and increase.
- C decreases, and increase.
- D increases, and decrease
Correct answer
B. decreases, and increase.
Step-by-step solution
Total energy of electron is stated as , potential energy and kinetic energy is given by .
So, as electron makes transition to higher level, total energy and potential energy increases due to the negative sign while the kinetic energy of electron decreases.
