Protons (the number on the right of calcium-40 represents number of protons). The tiniest component of ordinary matter, an atom, makes up a chemical element.
Neutral or ionized atoms make up every solid, liquid, gas, and plasma. Atoms typically have a diameter of 100 picometers or less. Due to quantum effects, they are so small atoms that it is impossible to precisely anticipate their behavioral using traditional physics, as if they were tennis balls, for example.
