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
