1. The problem statement, all variables and given/known data A hydrogen atom has a diameter of approximately 1.06x10^-10 m, as defined by the diameter of the spherical electron cloud around the nucleus. The hydrogen nucleus has a diameter of approximately 2.40x10^-15 m. (a) For a scale model, represent the diameter of the hydrogen atom by the 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? 2. Relevant equations 2.40x10^-15 (1000mm/1m) = 2.40e-12 V=(4/3)*pi*r^3 3. The attempt at a solution For (a) I got 2.40e-12 It says "Your response differs from the correct answer by orders of magnitude." For (b) I got 4.42e4 It says "Your response differs from the correct answer by orders of magnitude." Any help would be greatly appreciated!!
