Basically any atom has both protons and electrons in a equal number. That balances the + and - charges, so the net charge is zero. If you add an electron, the net negative charge changes and gains a negative value. If you instead remove an electron, the atom gains positive charge. This is what is known as 'effective nuclear charge'.The effective nuclear charge changes relatively little for electrons in the outermost, or valence shell, from lithium to cesium because electrons in filled inner shells are highly effective at shielding electrons in outer shells from the nuclear charge. Even though cesium has a nuclear charge of +55, it has 54 electrons in its filled 1s 2 2s 2 2p 6 3s 2 …. Clock spider
