Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...
