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)...

Each of the statements below attempts to explain why some periodic property varies predictably among elements in the periodic table. Determine if each statement is true or false. True False Within a family, elements with higher atomic numbers have atoms of larger radius because the atoms have lower effective nuclear charge. True False Within a period, elements with lower atomic numbers have lower electronegativity because the valance electrons are in higher principal energy levels. True False Within a family, elements with lower atomic...
