Ionized helium atom
Web19 apr. 2011 · Helium is a hydrogen-like atom. Using the fact that the ground state energy of hydrogen is 13.6eV, we can use the relation: E = 13.6eV (z^2/n^2) to calculate the energy levels of helium, where z is charge number and n^2 is the principle quantum number. For Helium z = 2, and in our case n1 = 6 and n2 = 2. Therefore, WebIn 1907, Rutherford and Thomas Royds used spectroscopy methods to show that positively charged particles of α α-radiation (called α α-particles) are in fact doubly ionized atoms of helium. In 1909, Rutherford, Ernest Marsden, and Hans Geiger used α α -particles in their famous scattering experiment that disproved Thomson’s model (see Linear Momentum …
