Lewis Structures
Group 13
Because each of the elements have the same number of valence electrons, their Lewis Structures have the same shape when bonded with the same element.

Period 7
Most of the elements in this period have either one or two valence electrons. Despite the transition metals having an uncertain number of valence electrons, they will most likely give away [rather than take] or share electrons.
