In an atom an electron excites to the fourth orbit. When it jumps back to the lower energy levels a spectrum is formed. Total number of spectral lines in this spectrum would beAn alpha particle with kinetic energy K approaches a stationary nucleus having atomic number Z . The distance of closest approach is b . Therefore the distance of closest approach According to Bohr's theory the ionization energy of H atom is 13.6 eV . The energy needed to remove an electron from Helium ion ( He ⁺ ) isAn electron in hydrogen atom jumps from a level n=4 to n=1 . The momentum of the recoiled atom isIt is observed that some of the spectral lines in hydrogen spectrum have wavelengths almost equal to those of the spectral lines in He ⁺ ion. Out of the following the transitions iA stationary hydrogen atom emits photon corresponding to the first line (highest wave length) of Lyman series. If R is the Rydberg constant and M is the mass of the atom, the recoiA stationary hydrogen atom emits a photon of wavelength 1025 Å . Its angular momentum changes byPositronium is a short-lived ( 10⁻⁹ ~s ) bound state of an electron and a positron (a positively charged particle with mass and charge equal (in magnitude) to an electron) revolvin Full Atomic Physics list All Olympiad workbook PYQs
