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.

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 numbers have lower ionization energy because the valance electrons are in lower principal energy levels.
True False  Within a family, elements with higher atomic numbers have higher electronegativity because the valance electrons are in lower principal energy levels.
True False  Within a family, elements with lower atomic numbers require more energy to remove an electron from the atom, because the atoms have higher effective nuclear charge.
True False  Within a period, elements with lower atomic numbers pull less strongly on electrons in a bond because the atoms have lower effective nuclear charge.

Currently, I have this but believe it is incorrect:

1. False 2. True 3. False 4. False 5. True 6. False
