Profit is producer surplus, minus fixed costs. In other words, its price minus variable costs. Profit, however, is price minus total cost. Since fixed cost is never negative, profit will always be less.
The atom is about 10-10 meters (or 10-8 centimeters) in size. This means a row of 108 (or 100,000,000) atoms would stretch a centimeter, about the size of your fingernail. Atoms of different elements are different sizes, but 10-10 m can be thought of as a rough value for any atom.
How small? Let's compare the size of a hydrogen atom to the size of a penny. Once again, Wikipedia to the rescue telling us that a U.S. penny is 19.05 mm in diameter (1.9 x 10-2 m).(1.9 x 10 -2 m / 1.1 x 10-10 m) = 172,727,273. 1.9 x 10 -2 m x 172,727,273 = 3,281,818 m = 3,281 km. For reference, the diameter of the Moon 3,475 km.et's compare the size of a hydrogen atom to the size of a penny.
