Reactivity changes within the group.

Reactivity of an element depends on the electrons in the outermost shell.

Copper Can be found as

native copper or part of a mineral

USES•65% for electrical purposes•24% for construction•CoinsFUN FACTS

•Statue of Liberty is made of more than 8o tons of copper•80% of all copper produced is still being used through recycling•Gold is so soft that a little copper is always added

Silver Silver is found in

native form, as an alloy with gold and in ores

USES• Jewelry •Currency•Photography•Dentistry•Conductor

FUN FACTS•Best conductor of all elements •Throughout history more people have silver for money over gold•Peru and Mexico are largest producers

Gold

Occurs naturally in nature

USES•Jewelry •Coins•Silverware/ Plates•Awards•Dentistry

FUN FACTS•Gold about the size of your thumbnail can spread to fit a tennis court•Only metal that does not rust•One of the softest metals

Zinc

The element is normally found in association with other base metals such as copper and lead in ores

USES•Galvanize other metals to prevent corrosion•Paints•Rubber Products

FUN FACTS•Last element alphabetically•In the body, can maximize physical growth and development•1 of 4 one syllable elements

Cadmium Found only in

compounds

USES•Mostly in batteries•Electroplating

FUN FACTS•Associated with TV’s•It is toxic•Almost all is contained by a by-pruduct

MercuryFUN FACTS

So thick that bricks can float in it

Gold dissolves in it Very toxic Liquid metal

•Found both by itself and as a compound in nature

USES•Thermometers•Barometers•For production of chlorine
