Carbon | Wiki | Everipedia

Carbon''s wiki: Carbon (from Latin: carbo "coal") is a chemical element with syol C and atomic nuer 6. It is nonmetallic and tetravalent —making four electrons available to form covalent chemical bonds.It belongs to group 14 of periodic table .Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radionuclide, decaying with a half-life of about 5,730 years.

Some Important Compounds of Boron - Study …

Indeed, boron nitride might be the hardest known substance. Both compounds have high melting points: for boron carbide 2,350°C (4,300°F) and for boron nitride more than 3,000°C (5,400°F). The above-mentioned properties make boron carbide and boron nitride valuable as abrasives and refractories. A grating is a fine material used to polish or
