Interesting facts about Silicon It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It was discovered and first isolated by Jöns Jacob Berzelius in 1823. Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. It is the second most abundant element in the Earth's crust (about 28% by mass), after oxygen.  The base material for silicon-based discrete components and integrated circuits is used in virtually all modern electronic equipment. Due to its semi
