Explanation:
Detailed explanation-1: -A metal has these properties : shiny, brittle, good electrical conductivity, and high melting point.
Detailed explanation-2: -Nonmetals – elements that are usually gases or solids at room temperature. Solid nonmetals are not malleable or ductile, but brittle or powdery. Nonmetals are poor conductors of heat and electricity, because electrons are not free to move.
Detailed explanation-3: -Metalloids are the smallest class of elements, containing just six members: boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). Metalloids have some properties of metals and some properties of nonmetals. Metalloids also tend to be shiny like metals, but brittle like nonmetals.
