Question

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. Within a family, elements with higher atomic numbers require more energy to remove an electron from the atom, because the atoms have higher effective nuclear charge.

Within a period, elements with lower atomic numbers have atoms of larger radius because the valance electrons are in higher principal energy levels.

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

Within a family, elements with lower atomic numbers have lower ionization energy because the valance electrons are in lower principal energy levels.

Within a family, elements with lower atomic numbers have atoms of smaller radius because the valance electrons are in lower principal energy levels.

Within a family, elements with higher atomic numbers pull less strongly on electrons in a bond because the valance electrons are in lower principal energy levels.
