| Boron Group |
| |
The Boron group is the series of elements in group 13 (IUPAC style) in the periodic table. These elements are characterized by having three electrons in their outer energy levels (valence layers). Boron is considered a metalloid, and the rest are considered metals of the poor metals group.
The boron group consists of boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and ununtrium (Uut) (unconfirmed).
Boron occurs spasely probably because of disruption of its nucleous by bombardment with subatomic particles produced from natural radioactivity. Aluminum occurs widely on earth and in fact, it is the third most abundant element in earth's crust (7.4%).
