Question:

(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 a particles?
(b) Consider the 23Na atom. Given that the radius and mass of the nucleus are 3.04 x 10-15 m and 3.82 × 10-23 g, respectively, calculate the density of the nucleus in g/cm3. The radius of a 23Na 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? [
