Silver:
Silver is the 47th element in the "Periodic table of the
elements". The chemical symbol is Ag. In history silver was
never as important as gold. It is 40 times cheaper than gold. Silver
reacts strong with other materials. After many years silver cutlery
for example is covered in a dark patina. To prevent the formation of
patina Roman and Greeks covered some things of silver in a very thin
gold layer, which is so thin that it is invisible. So the shining of
the silver stays. The part of silver in an alloy is declared in
thousendth parts. Fine silver consists of 999.9 thousendth part of
silver and sterling silver consists of 925 thousendth part of silver.
Silver is hauled in many countries. Silver is the best electrical and
thermical conductor.
