Answer Bank Elements in group 1A (1) of the periodic table will gain one electron to form an octet. Atoms with eight valence electrons follow the octet rule. Atoms can only gain electrons to obtain an octet. Elements in group 1A (1) of the periodic table will lose one electron to form an octet. All of the elements in group 8A (18) of the periodic table...

State true or false for the following: 1.Within a period, elements with higher atomic numbers require more energy to remove an electron from the atom, because the atoms have higher effective nuclear charge. 2.Within a family, elements with higher atomic numbers require more energy to remove an electron from the atom, because the valance electrons are in lower principal energy levels.3. Within a family, elements with lower atomic numbers have higher electronegativity because the atoms have higher effective nuclear charge.
