Period 2 element a supplement for the prevention and treatment of osteoporosis and arthritis. Carbon is the chemical element with atomic number 6, occurring as C, C and C. At standard temperature and pressure, carbon is a solid, occurring in many different allotropes, the most common of which are graphite, diamond, the fullerenes and amorphous carbon. Graphite is a soft, hexagonal crystalline, opaque black semimetal with very good conductive and thermodynamically stable properties. Diamond however is a highly transparent colourless cubic crystal with poor conductive properties, is the hardest known naturally occurring mineral and has the highest refractive index of all gemstones.

Transuranium element found. Transuranium elements may be utilized to synthesize other super-heavy elements. Elements of the island of stability have potential important military applications, including the development of compact nuclear weapons. The potential every-day applications are vast; the element americium is utilized in devices like smoke detectors and spectrometers. Transuranium element The transuranium elements (also known as transuranic elements) are the chemical elements with atomic numbers greater than 92, which is the atomic number of uranium. All of these elements are unstable and decay radioactively into other elements. Of the elements with atomic numbers 1 to 92, most can be found in
