Group 13 Elements

In the periodic table, group 13 elements exist in the first p-block. There are six elements present in group 13, which include boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and element 113 (ununtrium, (Uut)). Group 13 elements are also designated as the boron family.
