Nitrogen triiodide print that page

Nitrogen triiodide was first characterized by X-ray crystallography in 1990 when it was prepared by an ammonia-free route. Boron nitride reacts with iodine fluoride in trichlorofluoromethane at −30 °C to produce pure NI 3 in low yield: [ 1 ] BN + 3IF → NI 3 + BF 3 NI 3 is pyramidal

Nitrogen print that page


Many industrially important compounds, such as ammonia , nitric acid , organic nitrates ( propellants and explosives ), and cyanides , contain nitrogen . The extremely strong bond in elemental nitrogen dominates nitrogen chemistry, causing difficulty for both organisms and industry in breaking

Iodine in biology print that page

Iodine's main role in animal biology is as constituents of the thyroid hormones , thyroxine (T4) and triiodothyronine (T3). These are made from addition condensation products of the amino acid tyrosine , and are stored prior to release in an iodine-containing protein called thyroglobulin

Osmium print that page


Osmium is the densest metallic element and has a blue-gray tint. It is a hard but brittle metal that remains lustrous even at high temperatures. Because of its hardness , brittleness, low vapor pressure (the lowest of the platinum group metals), and very high melting point (the fourth highest

Explosive material print that page


An explosive material , also called an explosive , is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light , heat , sound , and pressure . An explosive charge is a measured

Boron nitride print that page


nitride is a chemical compound with chemical formula BN, consisting of equal numbers of boron and nitrogen atoms. BN is isoelectronic to a similarly structured carbon lattice and thus exists in various crystalline forms . The hexagonal form corresponding to graphite is the most stable
