WebAnd if you were to go a step farther with helium, you would get 1s2, because it has two electrons in that s orbital. Now for a more complicated atom. Let's do oxygen. Okay, 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 ... WebMay 25, 2013 · Electrons are particles that have a negative charge equal to -1. Therefore, an element in a neutral state will have the same number of protons and electrons.
