Metals

Properties of Metals Metals appear to the left of the dark ziz-zag line on the periodic table. Most metals are solid at room temperature.

Properties of Metals Metals have luster. This means they are shiny Metals have luster. This means they are shiny

Properties of Metals Ductile metals can be drawn into wire. Ductile metals can be drawn into wire.

Properties of Metals Malleable metals can be hammered into sheets Malleable metals can be h ammered into sheets

Properties of Metals Metals have a high melting point. They are also very dense.

Properties of Metals Conductors Metals are good conductors of electricity and heat Conductors Metals are good conductors of electricity and heat

Properties of Metals A chemical property of metal is its reaction with water and oxygen. This results in corrosion and rust.

Nonmetals

Properties of Nonmetals Nonmetals occur to the right of the dark zig-zag on the periodic table. Although Hydrogen is in family 1, it is also a nonmetal. Many nonmetals are gases at room temperature.

Properties of Nonmetals Nonmetals do not have luster; they are dull.

Properties of Nonmetals Brittle Nonmetals are brittle so they break easily. This means nonmetals ARE NOT ductile or malleable. Brittle Nonmetals are brittle so they break easily. This means nonmetals ARE NOT ductile or malleable.

Properties of Nonmetals Nonmetals have low density.

Properties of Nonmetals They also have a low melting point. This is why they are poor conductors of heat and electricity.

3) Physical properties of metals and non metals :- k Metals k Metals are solids (except mercury). k Metals are hard (except sodium, potassium etc. k Metals have metallic lustre. k Metals have high melting points and boliling points. k Metals are malleable ( can be made into thin sheets). k Metals are ductile (can be made into thin wires). k Metals are good conductors of heat and electricity. k Metals are sonorus (produces sound). k Non metals k Non metals may be solids, liquids or gases. k Non metals which are solids are brittle (diamond is the hardest). k Non metals do not have lustre some have a dull luster. k Non metals have low melting points. k Non metals are not malleable. k Non metals are not ductile. k Non metals are bad conductors of heat and electricity (except graphite). k Non metals are not sonorus.
