Definition of Silicon

What is the definition of Silicon? It is a non-metallic element occurring extensively in the earth's crust in silica and silicates, having both an amorphous and a crystalline allotrope. The Physical and Chemical Properties are the characteristics of a substance, like Silicon, which distinguishes it from any other substance.  Most common substances exist as States of Matter as solids, liquids, gases and plasma. Refer to the article on Silicon for additional information and facts about this substance. Refer to the article on Silicon Element for additional information and facts about this substance.

 

Silicon Properties - What are the Physical Properties of Silicon?
What are the Physical Properties of Silicon? The Physical properties of Silicon are the characteristics that can be observed without changing the substance into another substance. 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:

What are the Physical Properties of Silicon?

Color Pure silicon is a hard, dark gray solid
Phase Solid
Luster A metallic shine or glow
*Allotropic Silicon has two allotropic forms, a brown amorphous form, and a dark crystalline form
Solubility Soluble in hydrofluoric acid and alkalis
Melting point Melts at 1417C
Boiling point Boils at 2600C
Conductivity It is a semi-conductor

*Allotropic - Allotropes are forms of an element with different physical and chemical properties occurring in two or more crystalline forms in the same physical state.

Silicon Properties - What are the Chemical Properties of Silicon?
What are the Chemical Properties of Silicon? They are the characteristics that determine how it will react with other substances or change from 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:

What are the Chemical Properties of Silicon?

Chemical Formula Si
Compounds Silicon forms compounds with metals (silicides) and with non-metals
Oxidation 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 film
Flammability Dark-brown crystals that burn in air when ignited
  Is transparent to long-wavelength infra-red radiation
Reactivity with acids Dissolves only in a mixture of nitric acid and hydrofluoric acid
