WebThe oxygen atom has therefore 8 neutrons, 8 protons and 8 electrons. The number of valence electrons is equal with the group number. Since oxygen is in group 6 it means that it has 6 valence electrons. Check out the periodic table from the web site above. You will see that the number of protons and electrons are easy to determine. 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.
