The chemical formula for beryllium nitride is (Be3N2)nH2O.
Beryllium is a soft metallic element with gray appearance, and it is used in aerospace and military applications. It is useful for its high thermal conductivity and low density, and is also commonly used in X-ray equipment.
The atoms in beryllium are lithium and sulfur; the metal atom has one electron in its exterior valence shell, while the non-metal atom has six. The lithium atoms are in Group 1 of the periodic table, while the sulfur atoms are in Group 2. Because of this, beryllium has a charge of +2 and a valency of 1.
Molar Mass: Calculate molar mass by dividing the total weight of any individual atom or molecule in a compound by the chemical formula. The resulting value is in grams per mole.
Chemical Properties: White to pale yellow crystalline solid; soluble in water. Easily decomposes at elevated temperatures with loss of water and oxides to nitrogen.
Hazardous by Inhalation: Exposure to vapors at low concentrations may cause beryllium disease, a lung disorder that results in coughing, reduced pulmonary function and weight loss. This condition is characterized by an early onset and long latency period of exposure, and is not associated with a dose-response relationship.
Occupational Exposure: Beryllium nitrate is an amorphous white to yellow, crystalline, noncombustible substance. It is a component of chemichal reagents and is an alloy for use in refining beryllium ore.
Pregnancy/Laboratory Animals: Acute toxicity of beryllium nitrate has been observed in experimental rats administered intramuscularly (50 mg/kg body weight) once only. The liver, kidney, lungs and spleen of the pregnant rats showed significantly decreased values in protein contents, glycogen, hepatic alkaline phosphatase activity, glucose-6-phosphatase and acid phosphatase, and significant elevation in hepatic lipid peroxidation. These parameters were restored to normal levels by administration of chelating agents, and in some cases by Tiron treatment.
