Item 14
Rutherford's Planetary Model of the Atom In 1911, Ernest Rutherford
developed a planetary model of the atom, in which a small positively
charged nucleus is orbited by electrons. The model was motivated by an
experiment carried out by Rutherford and his graduate students, Geiger and
Marsden. In this experiment, they fired alpha particles with an initial speed
of 1.30 x 107m/s at a thin sheet of gold. (Alpha particles are obtained
from certain radioactive decays. They have a charge of +2e and a mass of
6.64 × 10-27 kg.)
Part A
r =
How close can the alpha particles get to a gold nucleus (charge = +79e), assuming the nucleus remains stationary? (This calculation sets an upper limit on the size of the gold
nucleus. See Chapter 31 of the textbook for further details.)

He asks, Why would atoms bond into solids rather than just floating freely with respect to each other? To help him understand at least one type of bonding in solids, you decide to embark on an energy explanation. You show him a drawing of a primitive cell of a sodium chloride crystal, NaCl, or simple table salt. The drawing is shown in Figure P24.10, where the orange spheres are Na+ ions and the blue spheres are Cl ions. Each ion has a charge of magnitude equal to the elementary charge e. The ions lie on the comers of a cube of side d. You explain to your roommate that the electrical potential energy is defined as zero when all eight charges are infinitely far apart from each other.
