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.

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.
Boron Model
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.

The boron atom consists of 3 electrons in its valence shell i.e. L shell. This allows us to easily draw the Lewis structure of Boron in which the nucleus is represented using the atomic symbol of the element and the valence shell electrons are presented in the form of dots around the nucleus. Therefore, the Lewis structure of Boron can be drawn as:

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.

The mass of one atom is usually expressed in atomic mass units (amu), which is referred to as the atomic mass. An amu is defined as exactly 1/12 1 / 12 of the mass of a carbon-12 atom and is equal to 1.6605 × × 10 −24 g. Protons are relatively heavy particles with a charge of 1+ and a mass of 1.0073 amu.

Boron group element - Properties, Uses, Atomic Structure: The table gives a list of some properties of the boron group elements. The ionization energies suggest that the formation of salts of the M2+ ions might be feasible. At first glance, such appears to be the case, since gallium compounds with the formula GaX2 (X representing chlorine, bromine, or iodine) can be made, and similar cases.

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.
