Detailed explanation-1: -Answer: Boron elements behave chemically both as metal and non metal.
Detailed explanation-2: -Therefore, the elements which behave as metals and non-metals are called metalloids.
Detailed explanation-3: -Boron is classified as a metalloid, having properties of both metals and nonmetals: it and conducts electricity at high temperatures; but at room temperature, is it an insulator.
Detailed explanation-4: -Metalloids share characteristics of both metals and non-metals and are also called semimetals.
Detailed explanation-5: -The atomic radius of boron is very small and it has relativey high nuclear charge and these properties are responsible for its non metallic character.
