A. Group A elements typically have one, two, or three valence electrons and Group D elements typically have five, six, or seven valence electrons. Therefore, ionic bonds would likely form between Group A elements and Group D elements, as Group A elements would likely lose electrons to achieve a stable octet and Group D elements would likely gain electrons to achieve a stable octet.
B. Group A elements have orbitals that are completely full in Group 8 (Noble Gases). This means that they have stable electron configurations and do not readily react with other elements. Their reactivity is low because they already have a full outer shell, so they do not need to gain or lose electrons to achieve stability.
12. A. According to the periodic table shown, describe what type of bonds would form between group A elements and group D elements?
B. Which group has orbitals that are completely full? How does this affect their reactivity? Why?
