Oxygen 18 number of protons
WebOxygen is the 8th element in the periodic table. This means that oxygen has 8 protons and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8). To get the number of valence electrons just look at the numbers above the oxygen on the periodic table.
