In Bohr's atomic model of hydrogen, let K,P and E 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 :
  1. All K,P and E increase.
  2. K decreases, P and E increase.
  3. P decreases, K and E increase.
  4. K increases, P and E decrease

Solution

Total energy of electron is stated as E=-Z2me48nhε02, potential energy P=-Z2me44nhε02 and kinetic energy is given by K=Z2me48nhε02.

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.
