Detailed explanation-1: -The border line elements-boron, silicon, germanium, arsenic, antimony, tellurium and polonium-exhibit properties similar to metals and nonmetals and are called metalloids.

Detailed explanation-2: -Some elements show the properties of both metals and non-metals like silicon, germanium etc falls under the category of the metalloid.

Detailed explanation-3: -The elements boron, silicon, germanium, arsenic, antimony, and tellurium separate the metals from the nonmetals in the periodic table. These elements, called metalloids or sometimes semimetals, exhibit properties characteristic of both metals and nonmetals.

Detailed explanation-4: -Metalloids have some properties of metals and some properties of nonmetals. Metalloids also tend to be shiny like metals, but brittle like nonmetals. Group 13 of the periodic table is called the boron group because boron (B) is the first element at the top of the group.
