WebBoron is quite distinct element in its group, as all other members of Group 13 are true metals. Boron exists in various allotropic forms (different forms of same elements that have different chemical and physical properties). Due to these allotropic forms, boron can exist as red crystals, black crystals or brown powder. ... WebThe element of group-13 is boron. Boron reacts with the oxygen atom to form oxide compounds. 4B + 3O 2 → 2B 2 O 3. From the top to the bottom of the group, the acidity of the element decreases, and the alkalinity increases. Boron is the first and most important element in group-13. Therefore, the oxide of the boron atom will be acidic.
