WebDec 19, 2024 · One thought was that the number of electrons increases and hence the nucleus has to pull more electrons toward it so the pull becomes weaker This is not correct either; it is not even based on anything scientific. It sounds as if it's a human trying to lug a weight along, and a heavier weight is harder to move than a lighter one. WebIonization energies increase across a period (ie, as you move across a row in the periodic table). This is because the positive charge of the nucleus increases whilst the electrons remain at the same average distance, this makes it more difficult to pull an electron away from the nucleus and hence the ionization energy decreases.
