SILVER

Silver by some measure
is one of the metals which is more romanticised;
perhaps owing to the fact that it is one of the metals
that is unreactive enough so that it occurs in nature in some quantity. But
being a precious metal, like gold, silver is a rather rare element in nature.
And annoyingly for some number of people, since the industrial revolution, which
has put a good chunk of pollutant gas into the atmosphere, the shine of silver
known to the ancients is now somewhat obscured by the tarnished, brown layer it
forms upon reaction with atmospheric sulphur. Silver
is unreactive, but still manages to sleep around the
periodic table and form compounds with a number of
elements. Such that the halides of silver seem to be a common point of teaching
in regards to teaching about the halogens and such.
Large deposits of silver exist in South America, and so goes the story that
some Europeans went in search for Silver in the most southern end of South
America, which was somewhat unsuccessful, but ended up influencing the name of
one of the largest countries on the continent; Argentina, whose name is derived
from the Latin name of silver, argentum. [Hence, Ag as its symbol]
Silver was one of the
first elements that came into the collection. The sample itself is not one to
write a whole lot about. It's a machined piece of silver foil, likely pretty
pure except for a contamination of whatever felt tip marker is made out of, since one of the sides of this thing has 'Ag'
written on it. So is a trend with some of the metals of the element collection
that were aquired pretty early
on. And I have a suspicion why - since these metals look pretty interchangeable
with each other, in a chemistry environment, particularly if you are not going
to be doing reactions with them where whatever felt tip marker
contains might contaminate the reaction, it can help to distinguish the
individual pieces of metal in some way. And felt tip marker seems to be a pretty efficient way of doing such thing.
More recently I have
acquired two 'silver coins'; one of the 20th century
which is 50% silver and one Victorian coin which is 92% or so. However both of these coins are too
big to fit in the vial, so they are stored separately. But perhaps some day I will get a coin that is small enough
so it fits...
