The more an element is to the left of the Periodic table, the more it is metal. The more an element is to the right the more it is non-metal. The more an element is to the top the more it po...Bonding - BoronCovalent bonds are formed between non-metal elements. They bond by sharing valence electrons (electrons on the outer shell). Covalent compounds do not conduct electricity, are usually gases or liquids, and have low melting and boiling points. Metallic bondingBoron Family: Group 13 Elements, Occurence, Properties ...They are boron (B), aluminium (Al), gallium (Ga), Indium (In), thallium (Tl), and element 113. This element gets the name of ununtrium [Uut]. The commonest property of the group is that each one of the elements has three electrons in the outer shell of their nuclear structure. Boron is the lightest of the elements in this group. It is a non-metal.
