is silicon dioxide SiO2, it occurs in a crystalline
state, an amorphous (shapeless) state and in impure forms such as
quartz, opal and sand, respectively. " In the form of silicates
it is present in most natural water supplies. Typical concentrations
lie between 1 and 30 mg/L. Higher concentrations may exist in
brackish waters and brines. "
is a "nonmetallic
element that occurs combined as the most abundant element
next to oxygen in the earth's crust and is used especially in alloys
and electronic device" (Merriam-Webster).
It may not BE a metal but it is considered semi-metallic. In other
words, "Silicon doesn't occur in the free, elemental state, but
is found in the form of silicon dioxide and complex silicates".
It was "discovered" in 1824 by Jons Jacob Berzelius.
"Silicon is important in plant and animal life. Diatoms in both
fresh and salt water extract silica from the water to use as a
component of their cell walls."(1)
Silicon is used in many household items such as transistors, micro
chips and electronics. Hence, Silicon Valley - the computer capital.
any of the [ :various polymeric organic

also found in processed foods, cosmetics, medications and all sorts
of products that you are exposed to and ingest on a daily basis. It
is also used to lubricate medical devices such as tubing, hypodermic
needles and is found in the food industry as being used to lubricate
blenders, frozen drink machines, piping, cooking utensils, and
Silicones are synthetic
polymers and are made by combining oxygen and silicon and in high
temperatures and pressures can produce polydimethylsiloxane (PDMS).
The fluids are made from linear chains of PDMS whereas the gels are
lightly cross-linked to give it a thicker cohesive-ness. The
elastomer implant implants contain very little free PDMS so that it
remains a solid.
