n.SymbolB A nonmetallic element that is amorphous and brown or crystalline and black, and is extracted chiefly from kernite and borax and used in flares, propellant mixtures, nuclear reactor control elements, abrasives, and hard metallic alloys. Atomic number 5; atomic weight 10.811; melting point...
Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust. It constitutes about 0.001 percent by weight of Earth...
The boron is indicated in the periodic table with B symbol and its atom number is 5 and the atomic weight is 10,81. The boron element, which has semi-metallic and semi-conductive properties, is contained in group 3A of the periodic table. Boron consists of two stable isotopes, called B10...

Boron is a chemical element with the symbol B and atomic number 5, found in nature primarily in compounds such as borax and boric acid. Boron is used in the manufacturing of glass and ceramics because it modifies the structure of glass, making it more resistant to thermal shock and chemicals...
Boron is an element of chemistry that has atomic number 5. The chemical symbol of elemental boron is B. It is dark in colour, brittle, lustrous metalloid in its crystalline form on the other side; when it is amorphous boron, it is found in powder form coloured in brown. It is one of...
