Solution

Metalloid
Elements showing properties of metals and non-metals are known as metalloids.
Common metalloids are Boron, Silicon, Germanium, Arsenic, Antimony and Tellurium.
Some metalloids that can conduct electricity are called semiconductors.
Carbon
Carbon is not an intrinsic semiconductor.
Carbon is a non-metal, and non-metals, due to their bond structure, are poor conductors of electricity.
Silicon and germanium are categorized as metalloids and belong to Group IVA, which is made of semiconductors.
Metalloids have properties that are similar to both metals and non-metals.
