Answer 1

The correct answer is Metalloid.

Key Points

A metalloid is a chemical element that displays characteristics of both metals and non-metals.
It was discovered by Franz Muller von Reichenstein in 1782.
Its atomic no. is 52 and its atomic mass is 127.6 g.mol^-1
Its melting and boiling points are 450⁰C and 1390⁰C respectively.
It is used for making iron stainless steel, lead, and copper alloys.

Additional Information

Metals: Metals are lustrous, sonorous, ductile, malleable, and high conductors of heat and electricity.
Non-metals: Non-metals are non-lustrous, neither malleable nor ductile, and poor conductors of heat and electricity.
Metalloid: Metaloid is a chemical element that displays characteristics of both metals and non-metals. These elements typically have some metallic properties but also share some properties with non-metals. Metalloids are located along the diagonal line separating metals from non-metals on the periodic table.
