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.
Atoms are made up of three smaller subatomic particles: protons, neutrons, and electrons. Nucleus: the tiny, dense, positively charged center of an atom. â¢protons and neutrons are in the nucleus. â¢makes up over 99.9% of an atomâs mass. â¢if an oxygen atom was as big as a stadium, its nucleus would be the size of a grape.
