Considering carbon (carbon is the key to life)– The electron configuration of the chemical element describes the ground state, i.e. the Next electron shell, which for Oxygen is the valence shell, there are six valence electrons, not filling it completely, due to needing two more. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers.
