WebJan 18, 2024 · Question 9. When the number of nucleons in nuclei increases, the binding energy per nucleon numerically. (a) increases continuously with mass number. (b) decreases continuously with mass number. (c) First increases and then decreases with increase of mass number. (d) Remains constant with mass number. Answer. WebNuclear charge is defined as the net positive charge experienced by an electron in the orbital of an atom exerted by the nucleus of the atom. Silicon has a greater nuclear charge than aluminium .. Hence, the effective nuclear charge exerted on the unpaired 3p electron of silicon would be greater as compared to that of aluminium.
