A material that does not conduct heat or electric current

• element

• ductility

• malleability

• insulator

elements that are typically solid, shiny, malleable, and good conductors of heat and electricity; includes most elements

• metals

• metalloids

• conductivity

• nonmetals

elements that are typically not shiny (dull), not malleable, and poor conductors of heat and electricity; usually gases or brittle solids

• metalloids

• nonmetals

• streak plate

• metals

elements that have properties of both metals and nonmetals; sometimes referred to as

semiconductors
