If the outermost electrons in cesium experienced the full nuclear charge of +55, a cesium atom would be very small indeed. In fact, the effective nuclear charge felt by the outermost electrons in cesium is much less than expected (6 rather than 55). Compared to their atoms, cations have the same number of protons but fewer electrons. Removal of electrons from an atom to form a cation results in a significant increase in effective nuclear charge, resulting in all other electrons being more strongly attracted to the nucleus. The result is a contraction in size from the atom to cation.The effective nuclear charge (Z eff) for the respective spinor/orbital. Effective charges for the outermost ns and np shells.
