Answer :
Answer:
Because their properties like conductivity, electronic configuration and ionization lies in between the metals and nonmetals.
Explanation:
There are a total of six elements that fall in the category of semiconductors.
Namely these are boron, silicon, germanium, arsenic, antimony, and tellurium.
These elements look like metals i.e. are lustrous but do not conduct electricity so well like a metal does.
Their chemical behavior falls between that of metals and nonmetals. For example, the pure metalloids form covalent crystals like the nonmetals, but like the metals, they generally do not form mono-atomic anions.
