Question
Transcribed Image Text:1. In the Bohr model for a hydrogen atom, an electron revolving in the third excited state. If
the electron drops into second state, calculate the following:
a. The total energy of the electron in the second excited state.
b. The transition energy.
c. The kinetic energy of electron in first excited state.
2. Prove that the total energy of electron is measured in units of joule.
3. Calculate the radius of orbit of an electron moving around a hydrogen atom with energy of
-13.6 eV. If a photon of energy 10.2 eV hits electron and losses all its energy to the electron.
Calculate the new radius of orbit.
4. An electron at rest hit by light of wavelength 4.96*10"m. Calculate the velocity of the
electron.
5. A single electron orbits around a nucleus of charge (+Ze). It requires 47.2 eV to excite the
electron from third Bohr orbit to the second orbit, calculate:
a. The value of Z.
b. The radius of the first excited orbit.
