Metals and Nonmetals

What are the properties of metals? Good conductors (easily transfer heat and electrical current) Shiny luster Malleable (can be hammered flat without breaking) Ductile (can be drawn into wires)

Conductivity What are some examples of good conductors? Why don’t you want to put your tongue on metal outside in the winter?

Luster: how something reflects light Metals aren’t always shiny, but often are. Look around the room and pick out 5 things that are metal

Malleability

Ductile- can be drawn out into long wires

Solids at room temp. All metals are solid at room temp. with the exception of Mercury (Hg).

Metals are reactive

Where are metals located on the periodic table?

Nonmetals Exactly the opposite of metals! NOT - shiny NOT - ductile NOT – conductive NOT – malleable NOT – magnetic Can be found as solids liquids or gasses Often dull and brittle

Metalloids Share properties of both metals and nonmetals Examples include silicon, carbon, and sulfur
