Physical Properties to classify Metals, Nonmetals & Metalloids by.

Physical Properties to classify Metals, Nonmetals & Metalloids by.

Malleability • The ability of some metals to be bent or hammered into different shapes.

Ductility • The ability of some metals to be pulled or twisted into wire. • If it is ductile, it is also malleable.

Brittle • Breaks when you try to bend or twist it.

Luster • Shines like the leg of your desk. • Metallic Luster • High Luster = metallic, very shiny • Dull Luster = metallic, not shiny • No Luster = no metallic shine

Conductor • Good Conductor - Allows heat and/or electricity to easily pass through. • Poor Conductor – Allows a little heat and/or electricity to pass through.

Semi-Conductor • Allows some heat/electricity to pass through.

Insulator • Keeps heat and/or electricity from passing through. • Opposite of a conductor.

MetalsNon-metalsMetalloids

Metals • Located on the left side of the zig-zag line • Solid at room temp. (except for mercury – Hg) • Good conductors of heat & electricity • Shiny • Malleable: Can be hammered into sheets • Ductile: Can be pulled into wire

Nonmetals • Located on the right side of the zig-zag line • Includes gases • Dull, Brittle – if solid • Not malleable and not ductile • Not good conductors (Are good Insulators)

Metalloids • Show characteristics of metals and nonmetals(ex: have a metallic luster but NOT be a good conductor of electricity.) • semiconductors of electricity(conduct electricity more easily than insulators and less easily than conductors)

Metalloids on the zig-zag line Tellurium Germanium Polonium Silicon Arsenic Boron Antimony Astatine
