Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?

If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
