Silicon is a typical semi-metal from the carbon group. It has properties of metals as well as non-metals and is considered a semiconductor. Pure silicon has a very low electrical conductivity. In contrast, its thermal conductivity is very high. Silicon is resistant to acids and water, but is soluble in hot alkaline solutions with the evolution of hydrogen. Silicon has 23 isotopes. Three of these are stable and occur in nature.
Pure silicon has the following properties:
