Example research essay topic: Analysis Of The Metal Silver’s Chemistry – 555 words

Hello my fellow readers. My name is Silver. My
name comes from the Anglo-Saxon word of Siolfur.
Some people call me Ag for short (Ag stands
argentum.) I am a white shinny metal. Since I am a
white shinny metal argentum is the Latin word for
white and shinning. I live in the periodic table
of elements and my address is 47. I usually weigh
107.868.

I am solid at room temperature. Copper
and gold are my good friends and they make me
strong and help me to be more durable. You can
find me almost anywhere. You can find me pure in
silver ores and you can find me in structure forms
in kitchens, jewelry stores, car shops, doctor
offices, dentist offices, banks, and even in
wallets. I am a very valuable metal. But although
you can find me most anywhere, only 16% of me is
used in coins and jewelry, while 40% is used to
make photographic film.

The rest of me is used in
industries and health services. I am even used to
make mirrors. I am only slightly reactive and
because of this I am placed very close to the
bottom of the reactivity chart. I have very little
uses in chemistry because of my low reactivity
status. I dont form oxides when I touch air but I
do form silver sulfide when I touch polluted air.
I form a tarnish when I interact with the hydrogen
sulfide in the air, especially near industrial
cities. The result of this is that I turn to
silver sulfide.

Tarnish is a dark, brown, or black
film that develops slowly on me. Some silver
tableware can tarnish because some food that you
eat contains hydrogen sulfide. Hard boiled eggs
are the perfect example of hydrogen sulfide. You
can also sometimes see it in the dark ring around
the yolk. Sterling and I are used to make jewelry,
cutlery and serving dishes. They are made of 92.5%
of me and 7.5% of copper.

Copper makes me harder,
stronger, and more durable. I lie between gold and
copper as one of the softest metals. Im the best
conductor of heat and electricity. My friends,
gold, platinum, mercury, and I make up the noble
metals. We dont oxidize readily when heated and we
dont dissolve in most mineral acids. I am a rare
element because Im the 68th in the elements in the
earths crust.

Because I am light sensitive, about
4/10 of me is used industrially to make film. The
film is made of a plastic base over which is
spread to a thin layer of gelatin that contains
silver salt. This gelatin layer is known as the
emulsion layer. Various salts are used in the
emulsion. In iodide form, I react fastest to light
and I am used for fast speed films. When I am in
bromide form, I am slightly less sensitive and I
am used for slower speeds.

Bromide and chloride
are light sensitive chemicals and are placed on
the surface of developing papers. My shell pattern
is 2-8-18-18-1. I have 25 known isotopes including
9 nuclear isomers. My weight ranges between
102-117. I dont react with diluted non-oxidizing
acids (hydro-chloric and sulfuric acids) or strong
bases (sodium hydro-oxide.) when I react with
oxidizing acids (nitric or soncentrated sulfuric
acids) I dissolve it and form a unipositive ion
(Ag+.).
