(a) Describe Rutherford's experiment and how it led to the structure of the atom. How was he able to estimate the number of protons in a nucleus from the scattering of the particles? (b) Consider the 2Na atom. Given that the radius and mass of the nucleus are 3.04 X 10-15m and 3.82 x 1024 g, respectively, calculate the density of the nucleus in g cm. The radius of a 2Na atom is 186 pm. Calculate the density of the space occupied by the electrons in the sodium atom. Do your results support Rutherford's model of an atom? (The volume of a sphere is r, where r is the radius.)
