2.04. Atomic Radius. 90 pm. Stable Isotopes. 10 B, 11 B. Boron is the only element in group 3 that is not a metal. It has properties that lie between metals and non-metals (semimetals). For example Boron is a semiconductor unlike the rest of the group 13 elements. Chemically, it is closer to aluminum than any of the other group 13 elements.

Amorphous boron is used in pyrotechnic flares to provide a distinctive green color, and in rockets as an igniter. By far the most commercially important boron compound in terms of dollar sales is Na 2 B 4 O 7 • 5H2O. Th i s pentahydrate is used in very large quantities in the manufacture of insulation fiberglass and sodium perborate bleach.. Boric acid is also an important boron compound.

What is Boron. Boron (pronunciation BO-ron [2]), represented by the chemical symbol or chemical formula B [1], is hard and brittle in its crystalline form [22].It has allotropes in the form of an amorphous powder and three major crystalline forms [34].Naturally occurring B has two stable isotopes with mass numbers 10 and 11 [1, 2].Besides that, it has 11 synthetic isotopes, some of which are.
Boron Element With Reaction, Properties, Uses, & Price Periodic Table
A possible crystal structure of Boron is rhombohedral structure. In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. A crystal lattice is a repeating pattern of mathematical points that extends throughout space. The forces of chemical bonding causes this repetition.

boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh). They are characterized as a group by having three electrons in the outermost parts of their atomic structure. Boron, the lightest of these elements, is a metalloid.

Atomic Structure of Boron The atomic number of the boron element is 5. The nucleus of this atom consists of six neutrons and five positively charged protons. Five electrons occupy available electron shells and revolve around the nucleus. The stability of the valence electrons determines the chemical and physical properties of the element.
