SSC MTS EXAM

Detailed explanation-1: -The metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. These elements look metallic; however, they do not conduct electricity as well as metals so they are semiconductors.

Detailed explanation-2: -The elements which are found in the step-like line between metals and nonmetals of the periodic table are known as the metalloids. They are: antimony (Sb), germanium (Ge), silicon (Si), arsenic (As), tellurium (Te), polonium (Po), boron (B), and astatine (At).

Detailed explanation-3: -How Are Elements Classified As Metalloids? Elements that exhibit both metal and nonmetal characteristics, but not solely one or the other, are typically classified as metalloid elements. They are also classified as metalloids based on their ionization energies and electronegativities.

Detailed explanation-4: -Their electronic structures are intermediate between those of metals and nonmetals. Thus, they conduct electricity better than nonmetals but not as well as metals.
