These four elements—oxygen, carbon, hydrogen, and nitrogen—together make up more than 95 percent of the mass of the human body, and the body cannot make elements, so it is helpful to have them in consumables. Oxygen has eight protons. In its most abundant stable form, it has eight neutrons, too, for a mass number of 16.
Hydrogen and oxygen are elements. What that really means is that when an atom, the fundamental unit that makes up everything, has 1 proton (a positively charged sub-atomic particle) it is a hydrogen atom, and when it has 8 protons, it is an oxygen atom.
