According to astrophysicist David Palmer, about 75 percent of all the known elemental matter that exists is composed of hydrogen. The nucleus of a hydrogen atom is made out of a single proton, which is a positively charged particle. One electron orbits around the outside of the nucleus. Neutrons, which can be found in all other elements, do not exist in the most common form of hydrogen.Hydrogen peroxide (H2O2) is produced predominantly in plant cells during photosynthesis and photorespiration, and to a lesser extent, in respiration processes.
