EVERYDAY SCIENCE

Detailed explanation-1: -Silicon is made from sand, and it is the second most abundant element on earth after oxygen. Silicon wafers are made using a type of sand called silica sand, which is made of silicon dioxide. The sand is melted and cast in the form of a large cylinder called an ‘ingot’.

Detailed explanation-2: -Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it.

Detailed explanation-3: -a tiny wafer of semiconducting material used to make an integrated circuit. Thus chip has its normal meaning of “a small piece” (of silicon, in this case) and microchip is a tiny piece.

Detailed explanation-4: -Silicon is abundantly present and is the most utilized substance for the fabrication of computer chips. Silicon is a naturally occurring semiconductor. The injection of imperfections to silicon can change its electrical characteristics, a technique known as doping.
