The element cadmium, although not widely known,
is quit useful and is also important to our society.
Here are a few example of cadmium's historical background,
its technical data and the practical and every day uses of this element.

This historical background of cadmium started when
Friedrich Stormeyer, who was a significant scientist of
the eight-teenth century in Germany discovered it in 1817.
He obtained a sample of zinc carbonate for laboratory use
and use and observed that the odd samples changed colors
when they were influenced by heat. This was a characteristic
that did not exict in pure zinc caronate. The impurity of
the zinc carbonate let the curious scinetist to hypothesize that another
element was present in his sample. He eventually proved his educated
guess to be a silvery-gray metal, and is now known as Cadmium.
Thanks to stromeyer, scientits of today now know
that cadmium is usually found in very small quanities that
are associated with zinc ores. Cadium is very similar in
many aspects to zinc and should be handled with care because
of its toxic properties. It Is also a natural emement in the
earth's crust and has no definite taste or odor.
Cadiums chemical symbol is Cd and its atomic
number is 48. It has an atomic weight of 112.411 grams
and is in group 12 of the periodic table. The element
is in a solid state at room temperature and it's boiling
point is at 1038 Kelvin or 756 degrees celsius.
