WebCarbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons . History [ edit] Before 1959, both the IUPAP and IUPAC used oxygen to define the mole; the chemists defining the mole as the number of atoms of oxygen which had mass 16 g, the physicists using a similar definition but with the oxygen-16 isotope only. WebWhile most oxgen atoms have a mass of 16 (8 protons and 8 neutrons), a small number of oxygen atoms have a mass of 18 (8 protons and 10 neutrons). Both of these isotopes are stable; they do not undergo radioactive decay. Water molecules (H2O) in the ocean may contain either isotope, oxygen 16 or oxygen 18. What are 5 interesting facts about …
