Silver tarnishes slowly as sulfur compounds in
the atmosphere react with the surface to form
black silver sulfide. Silver has been used for
jewellery and tableware since ancient times, but
it is also employed for silvering glass and in
photography, as well as for industrial uses.
World production is about 10,000 tonnes per year.
Silver is present in the human body but has no
known role.

lanthanum
Discovered by C.G. Mosander in 1839
Rare earth
Origin The name is derived from the Greek
'lanthana, meaning to lie hidden.
161

• Lanthanum is one of the most reactive of the
  rare earth metals. It oxidises rapidly when
  exposed to the air, and burns easily. It is
  attacked slowly by cold water, and rapidly by hot
  water. It reacts directly with carbon, nitrogen,
  phosphorus, sulfur, the halogens and some other
  elements. At room temperature, the structure of
  lanthanum is hexagonal. This changes to
  face-centred cubic at 310K, and to body-centred
  cubic at 865K.
