Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Argon compounds, the chemical compounds that contain the element argon, are rarely encountered due to the inertness of the argon atom. 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. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.
