WebQ.21 An energy of 68 eV is required to excite a hydrogen like atom from its second Bohr orbit to the third. The nuclear charge is Ze. Find the value of Z, the kinetic energy of the electron in the first Bohr orbit and the wavelength of the radiation required to eject the electrons from the first Bohr orbit to infinity. WebEnergy of the nth Bohr's orbit is given by En = −13.6× Z2 n2 eV For H-atom, Z = 1 The difference in energy between the first and the second Bohr orbit: E2−E1= 13.6×12×( 1 12− 1 22) = 13.6× 3 4 eV The difference in energy between the second and the third Bohr orbit: E3−E2= 13.6×12×( 1 22− 1 32) = 13.6× 5 36 eV Taking the ratio, we get :

WebJul 20, 2024 · Example 21.4. 1: Emitted Photon. According to Bohr’s theory two of the allowed orbits in the hydrogen atom have radii of 52.918 and 211.67 pm. Calculate the energy, the frequency, and the wavelength of the photon emitted when the electron moves from the outer to the inner of these two orbits. WebThe Bohr radius is equal to: Q5. According to Bohr model the energy of the emitted photon due to transition from 3rd excited state to ground state is Q6. Consider an electron moving in orbit n = 2 in the Bohr model of the hydrogen atom. WebAs the electrons orbit, they should emit radiation and lose energy. They will spiral into the nucleus in about a nanosecond. Needless to say, this is not how atoms behave. The … nothing\\u0027s carved
