The
next best after gold is silver!! |
| HIstory |
| |
Silver has been used for over 500 years. It has been known since
ancient times and is mentioned in Genesis. Slag dumps in Asia
Minor and on different islands in the Aegerian sea prove that
people were able to separate silver from lead all the way back
to 3000 BC. A major watershed of silver production was the discovery
of the New world in 1942. Major silver mines in Mexico, Bolivia
and Peru were made, which led to major use and production of
silver. Advanced techniques evolved for extracting silver from
ore, and in the late 19th century and the early 20th centuries
the production of silver increased. Before the 1770’s
only about 25 percent of world silver production occurred. Today
you can find silver

| Uses |
 Here
is one use of silver.Silver helps make mirrors.
|
Silver can be found from ores and is usually combined with other
elements. Silver is used for many home and industrial uses,
such as making jewelry, silverware, mirrors, batteries, electricity
and heat. Amazingly enough silver is the best reflector. Silver
has been used for thousands of years as ornaments and untensils,
and for trade. For many years people considered silver to be
the second most precious metal. During the middle ages silver
goblets were used to drink out of, and they were believed to
prevent poisoning from contaminated water, or bad whine. Pure
silver was used as a liner in water canteens since the 1700’s.
The water in the canteens were fresh, sweet and clean until
dranken. No one really knows of any disease causing organism
that is in the element silver.

| Description |
| |
Silver has a metallic luster with a silver color. Silver is
a bit harder than gold, ductile and
malleable, and can tarnish. Pure silver
is almost white, and is an excellent conductor of heat and electricity.
Ozone, hydrogen sulffide, and air containing sulfar will cause
silver to tarnish. Sterling Silver is found in jewelry and silverware.
|
| Chemical Properties |
| |
Silver is only slightly reactive which
means silver compounds are rarely found in nature. Silver is
stable in clean air or water however it does react with polluted
air to form silver sulfide. Silver will dissolve in hot concentrated
sulpuric acid, and in diluted or concentrated nitric acid. |
