Hope this helps. WebGroup the following electron configurations in pairs that would represent elements with similar chemical properties. Valence electrons are the electrons contained in the outermost or valence shell of an atom or ion. This is a carryover from early spectroscopic nomenclature of the atom. Rum is a very reactive liquid. So far we have filled in four electrons. So it's actually going to have the exact same electron To calculate the electron configuration of elements, we will use the Aufbau principle, for that, we have to first find the total number of electrons in a given element, then we have to fill the orbitals with electrons from lower energy to higher energy, i.e. the electrons will be filled into 1s orbital first then 2s, then 2pso on. Not always. And so we're going to have argon and then we're going to have, Proton values are much harder to change and can only be modified with atomic (or nuclear) reactions, since they are packed in with the nutrons in the nucleus.
