WebApr 7, 2016 · Explanation: Effective nuclear charge is how attracted on particular electron is to the nucleus. It can be estimated by Zeff = Z −S where Zeff is the effective nuclear charge, Z is the atomic number and S is the number of "shielding" electrons. Web1) Atomic Size As the size of the atom increases, the distance between the nucleus and the last shell which receives the incoming electrons increases. This decreases the force of attraction between the nucleus and the incoming electron. Hence, the electron gain enthalpy becomes less negative. 2) Nuclear charge
