Lithium-Is-Part-Of-The-Alkali-Metals-In-The-Group -157

Text-only Preview

Lithium is part of the alkali metals in the group of
chemical elements. The atomic number of lithium is
3 and it is represented on the periodic table under
the symbol Li. It is silver-white in color and soft.
Lithium in standard conditions has the lowest
density of all solid elements and is also the lightest
of the metals. As with all of the alkali metals, lithium
is extremely flammable and reactive. This is why it is
usually stored in mineral oil.

The high reactivity of lithium means that it does not occur freely in nature and
is only seen in compounds Typically these compounds are ionic There are a
number of pegmatitic minerals that contain lithium However, because of its
water solubility, it is found in the ocean and usually gathered from clays and
brines For commercial use, lithium is electrolytically isolated from a mix of
potassium chloride and lithium chloride History In 1800, petalite, was found
by Jose Bonifacio de Andrada, a Brazilian It was found in Uto, Sweden within
a mine that is part of the island

However, Johan August Arfwedson discovered the new element in 1817 while
working in the lab of Jons Jakob Berzelius The new element would form
compounds that were similar to compounds formed by potassium and sodium,
but the hydroxide and carbonate were not as soluble in water, it was also more
alkaline Berzelius named the material "lithionlithina" which comes from the
Greek word lithos that means stone This was to reflect that it had been
discovered in a solid mineral This was different than potassium, which was
discovered in the ashes of plants and sodium that is highly abundant in the
blood of animals Production The production of lithium has increased greatly
since World War II ended Lithium salts are pulled from water in brine pools,
brine deposits, and from mineral springs

The metal can then be produced using electrolytic processes that use a
combination of potassium chloride and lithium chloride There are deposits of
lithium found throughout the Andes Mountains in South America Chili is the
top producer of lithium, with Argentina following Both of these countries get
the lithium from brine pools Within the United States, there are brine pools in
Nevada that lithium is recovered from Lithium Uses There are many
different uses of lithium

Lithium oxide can be used for improving the physical properties of glass and
ceramics Ovenware uses lithium oxides and is the largest use for lithium
compounds throughout the world In the late part of the 20th century, lithium
became an important anode material that is used for making lithiumion
batteries The high electrochemical potential of lithium allows it to generate
around 3 volts of energy compared to 2 1 volts that are generated from
lead/acid batteries or the 1 5 volts generated from zinc-carbon cells

Lithium is also commonly used in greases A strong base is made from
lithium hydroxide, which can be heated with fat to produce soap from the
lithium stearate The lithium soap can thicken oils, which is used silver stocks
