 20. A hydrogen atom has a diameter of 1.06 x10^-10 m as defined by the diameter of the spherical electron cloud around the nucleus. The hydrogen nucleus has a diameter of approximately 2.40x 10^-15 m . (a) For a scale model, represent the diameter of the hydrogen atom by the playing length of an American football field $(100$ yards $=300 ft$ ) and determine the diameter of the nucleus in millimeters. (b) The atom is how many times larger in volume than its nucleus?
