Question

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

True False  

Within a period, elements with lower atomic numbers have atoms of smaller radius because the atoms have higher effective nuclear charge.
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.
Within a family, elements with higher atomic numbers have lower electronegativity because the atoms have lower effective nuclear charge.
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.
Within a family, elements with higher atomic numbers have lower ionization energy because the valance electrons are in higher principal energy levels.

Answer 1

(1)-Within a family, elements with higher atomic numbers pull less strongly on electrons in a bond, because the valance electrons are in higher principal energy levels. Answer-TRUE-BECAUSE SHIELDING EFFECT OF HIGHER VALENCE ENERGY LEVEL IS LOW

(2)Within a period, elements with lower atomic numbers have atoms of smaller radius because the atoms have higher effective nuclear charge. Answer-FALSE-(REASON IS SAME AS ABOVE IN QUESTION 2)

(3)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. Answer-TRUE-(REASON IS SAME AS ABOVE IN QUESTION 3)

(4)Within a family, elements with higher atomic numbers have lower electronegativity because the atoms have lower effective nuclear charge. Answer- TRUE-REASON IS SAME AS ABOVE IN QUESTION 4.

(5)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. Answer-FALSE-(IT IS DIFFICULT TO REMOVE A VALENCE ELECTRON FROM LOWER ENERGY LEVEL)

(6)Within a family, elements with higher atomic numbers have lower ionization energy because the valance electrons are in higher principal energy levels. Answer-TRUE-(IT IS EASY TO REMOVE A VALENCE ELECTRON FROM HIGHER ENERGY LEVEL ALONG A FAMILY)
