A metalloid is a chemical element with properties that fall between those of metals and nonmetals. Key Points The elements that show properties that are intermediate between metals and non-metals are called metalloids. Metals include the alkali metal, alkaline earth, transition metal, basic metal, lanthanide, and actinide groups. Metals tend to lose electrons and form ionic compounds, while nonmetals usually gain or share electrons to form covalent bonds. It cuts through the metalloids, elements that share properties between metals and nonmetals, in an arbitrary manner, since the transition between metallic and non-metallic properties among these elements is gradual. Metalloids have properties of both metals and nonmetals and are good semiconductors. A metalloid is an element that has properties that are intermediate between those of metals and nonmetals.
