Solution

Metal, metalloid and nonmetal:

  • Metals are known as the compounds which have a tendency to donate electron, whereas the elements having gaining tendency of electron is known as nonmetals.
  • However, metalloids are known to be those elements which have both the properties of a metal and nonmetal.

Silicon is a metalloid:

  • The element Silicon is a chemical element with the chemical symbol Siand the atomic number of 14,which is also a hard, brittle crystalline solid with a blue-grey metallic luster.
  • It is known as a tetravalent metalloid and semiconductor.
  • Due to the fact that Silicon have only 4 electrons in its valence shell, hence it has the tendency to both accept and donate electron to complete its octet.
  • Which then explains , the tendency of Silicon to possess the properties of both metals and nonmetals, hence called as a metalloid.

Therefore, Silicon is explained known as a metalloid .
