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 v Within a family, elements with higher atomic numbers have higher ionization energy because the atoms have higher effective nuclear charge. False v Within a family, elements with higher atomic numbers have higher electronegativity because the valance electrons are in higher principal energy levels. False v Within a family, elements with lower atomic numbers require more energy to remove an electron from the atom, because the valance electrons are in higher principal energy levels. False v Within a period, elements with lower atomic numbers have lower ionization energy because the atoms have lower effective nuclear charge. False v Within a period, elements with lower atomic numbers have lower electronegativity because the atoms have lower effective nuclear charge. True v Within a period, elements with higher atomic numbers have atoms of smaller radius because the valance electrons are in higher principal energy levels. Submit Answer Incorrect.
