5. Sketch the planetary picture of the Helium Atom (Z=2, A=4). The radius of the electrons orbits in Helium (i.e. the size of the Helium Atom) is about Re = 2 x 10^-11m while the distance between the two protons is the nucleus is about Rff =2x10^-15m. Write down the ratio of the repulsive electric force between the two protons to the attractive electric force between the Helium nucleus and the electron R2 = RFF/F nucl. Judiciously do any possible...
