Periodic table group
Group 13
Group 13 is a vertical column of the periodic table containing Boron, Aluminum, Gallium, Indium, Thallium, Nihonium. Elements in the same group have the same number of valence electrons, which is why they show related chemical behavior. The boron group. Boron itself is a metalloid while the rest are metals, and the +3 oxidation state runs through the group's chemistry.
