ECHEMI Editorial ReferenceSelenium is a nonmetal (or semimetallic) element (also referred to as a metalloid). It belongs to Group 16 (Group VIA) of the periodic table, located between sulfur and tellurium.
The chemical properties of selenium are similar to sulfur. Selenium combines with metals and many nonmetals directly or in aqueous solution. It does not react directly with hydrogen fluoride or hydrogen chloride but decomposes hydrogen iodide to liberate iodine and yield hydrogen selenide. The selenides rCertificatesBasic Info-

XLogP3:5
Appearance:White to creamy white powder
Density:4.8 g/cm3
Melting Point:170-217 °C
Boiling Point:685 °C
Water Solubility:H2O: Insoluble
Storage Conditions:Storage temperature: no restrictions.
Vapor Pressure:<1 Pa (20 °C)
Toxicity:Intravenous-rat LD50: 6 mg/kg; inhalation-rat LDL0: 33 mg/m3/8 hours
Flammability characteristics:Combustible at high temperature; selenium oxide fumes are released in the fire
Explosive limit:During attempted conversion of recovered selenium metal to the dioxide by heating in oxygen, a vigorous explosion occurred. This was attributed to selenium-catalysed oxidation traces of organic impurities in the selenium. Oxidation of recovered selenium with nitric acid is rendered vigorous by presence of organic impurities, but is a safe procedure.
