It is the third most abundant element in the universe and the most abundant element in the human body. Oxygen has 8 electrons and 8 protons.
Essay Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth.
