21/3/2019· Properties Metalloids are brittle, lustrous metallic elements that exhibit semiconductive properties. Unlike metals, they are neither malleable nor ductile. Although they do not readily alloy with metals, each metalloid selectively compounds with certain metal elements to form alloys.
The elements can be classified as metals, nonmetals, or metalloids. Physical Properties of Metals Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
