PHYSICAL PROPERTIES are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Silicon are as follows:
Color : Pure silicon is a hard, dark gray solidPhase: SolidLuster: A metallic shine or glow*Allotropic: Silicon has two allotropic forms, a brown amorphous form, and a dark crystalline formSolubility: Soluble in hydrofluoric acid and alkalisMelting point: Melts at 1417°CBoiling point : Boils at 2600°CConductivity : It is a semi-conductor
Chemical Properties
What are the Chemical Properties of Silicon? They are the characteristics that determine how it will react with other substances or changefrom one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Silicon are as follows:
Chemical Formula : SiCompounds : Silicon forms compounds with metals (silicides) and with non-metalsOxidation : Combined with oxygen as silica (silicon dioxide, SiO2) or with oxygen and metals as silicate minerals. It is stable in air even at elevated temperatures owing to the formation of a protective oxide filmFlammability : Dark-brown crystals that burn in air when ignited : Is transparent to long-wavelength infra-red radiationReactivity with acids : Dissolves only in a mixture of nitric acid and hydrofluoric
