WebThe tiny superscripts say how many electrons live in each orbital, the letters represent the orbitals that are available, and the big numbers say which energy level the orbitals are found in. Remember that the total number of electrons just equals the total number of protons, and so the superscripts add up to 8, the atomic number of oxygen. WebJul 11, 2024 · Now we multiply all the protons and neutrons by three for the quarks, and we have our number. So how many are there? 3.28 x 10 80 .
