An element in group 0 has a full outer shell. top refereesWebOkay, so we know oxygen has 8 electrons, and only two electrons can exist in each orbital. So on the first energy level, we have 1s2, because it has at least as many electrons as helium. Now, there can be no p orbitals in the first energy level, so then we jump straight to the second.
