Question

A hydrogen atom has a diameter of approximately 1.06 ✕ 10-10 m, as defined by the diameter of the spherical electron cloud around the nucleus. The hydrogen nucleus has a diameter of approximately 2.40 ✕ 10-15 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.

Answer 1

diameter of the nucleus[{(2.4)/100000}/1.06]*300 ft = 0.0679 ft or 0.82 inch

Answer 2

2 millimeters
