Properties of Metals, Nonmetals, and Semimetals

METALS malleable, lustrous, ductile, good conductors of heat and electricity NONMETALS gases or brittle solids at room temperature, poor conductors of heat and electricity (insulators) METALLOIDS (Semi-metals) dull, brittle, semi-conductors (used in computer chips)

Metals, Nonmetals, and Semimetals

Semimetals (Metalloids)

– Exhibit properties intermediate between metals and nonmetals – Can bond with many different elements – Brittle – Somewhat reactive – Have a varying ability to conduct electric current (semi-conductors)
