Vedclass · Answer

(C) Boron is a metalloid,which means it exhibits properties intermediate between metals and non-metals. Thus,the Assertion is true.While boron shows some metallic character (like high melting point and hardness),it is primarily characterized by its non-metallic behavior in many chemical reactions. The statement 'Boron shows metallic nature' is too broad and does not explain why it is classified as a metalloid. In fact,boron is predominantly non-metallic in its chemical behavior. Therefore,the Reason is considered incorrect in the context of defining its metalloid nature.

Assertion : Boron is a metalloid.
Reason : Boron shows metallic nature.
