Oxygen-16 (16 O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus.It has a mass of 15.994 914 619 56 u.Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen's natural abundance. Oxygen is composed of 8 protons, and in its most common form with 8 neutrons, giving it an atomic weight of 16 (16 O) -- this is know as a "light" oxygen. So, the short answer is, pure oxygen is generally bad, and sometimes toxic. The number of valence electrons is equal with the group number. It is called "light" because a small fraction of oxygen atoms have 2 extra neutrons and a resulting atomic weight of 18 (18 O), which is then known as "heavy" oxygen. Because the atom is neutral, there are also 8 electrons. The number of protons. Protons and Neutrons in Oxygen Oxygen is a chemical element with atomic number 8 which means there are 8 protons in its nucleus. a) oxygen: atomic number = 8, atomic . Hence 8 protons. Elements are defined by the atomic number, the number of protons in the nucleus. Compared to protons and neutrons, the mass of an electron is very small. Problem AT2.1. Because protons and neutrons are roughly equal in mass, an isotope's number is equal to the sum of its protons and neutrons. Oxygen has the atomic number 8, which means the nuclei of its atoms have 8 protons. You will see that the number of protons and electrons are easy to determine.
