metalloid

an element that has proprieties of both metals and nonmetals

metals

an element that is generally shiny, ductile, malleable, and a good conductor.

dull

does not reflect light

brittle

easily broken

reflects light

metal

A class of elements characterized by physical properties that include shininess, malleability, ductility, and conductivity.

semiconductor
