Chemical Safety Card for Chlorine. International Chemical Safety Card for Chlorine. Asked By adminstaff @ 11/10/2019 07:25 PM. In this case, the atom with the largest atomic number will yield the greatest effective nuclear charge. This decreases the pull on valence electrons towards the nucleus, increasing the atomic radius of the atom and making the valence electrons easier to remove. The reason is that the atomic number increases across a period, thereby increasing the nuclear charge. Chemical Reference Data. The effective nuclear charge (often symbolized as Z eff or Z*) is the net positive charge experienced by an electron in a multi-electron atom . Cordero, Beatriz, Vernica Gmez, Ana E.
