rue False Within a period, elements with lower atomic numbers require more energy to remove an electron from the atom, because the atoms have lower effective nuclear charge. True False Within a period, elements with higher atomic numbers have higher ionization energy because the atoms have lower effective nuclear charge. True False 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
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.
