silicones are classified as metalloid as it is a semi conductor. moreover,they are water repellent,inert,can resist high temperature without decomposing,and are in the form of oil and wax....
Silicon is an element that has:

Facts=
On Earth, silicon is the second most abundant element (after oxygen) in the crust, making up 25.7% of the crust by mass.
*Silicon is found in the sun and the stars.
*Silicon transmits over 95% of infrared wavelength.
*Silicon is an important ingredient in steel.
*Diatoms in both fresh and salt water extract silica from the water to use as a component of the plant's cell walls.
*Today, silicon is purified by converting it to a silicon compound that can be more easily purified than in its original state.
freezing point is not found
I thought it was a large type of siloxanes that is stable for an overwide ranges of degree of temperatures. Also it's used in making body implants. thanks for a good Question.

It is an element, so it is not composed of elements, like molecules are (such as carbon dioxide).
So… it is composed of protons, neutrons and electrons (although this is true of every element, of course).
Silicon Sealer contains Silicon. Silicon sealer is a rubbery plastic used for sealing, E.g. Surfaces to Kitchen Walls.
Diamond is composed of the element carbon, and quartz is composed of the elements silicon and oxygen.
Silicon TetrafluorideSi-siliconeF=fluorine4=four
It is silicon and oxygen that make up sand. Most sand is silicon dioxide, or SiO2. Quartz is the most common of a family of minerals made up of silicon dioxide called silicates. It is one example of a form of silicon dioxide.
Silicate minerals are those composed of silicon and oxygen atoms. Some of these minerals are quartz, feldspar, mica and olivine.

Quartz is composed of silicon dioxide.
silicon is an element and is only composed of silicon
Silica is silicon dioxide
Diamond is composed of the element carbon, and quartz is composed of the elements silicon and oxygen.
No, a silicon dioxide molecule is composed of 1 silicon atom and 2 oxygen atoms.
silicon
The portion of Earth's crust which is composed of the element silicon is roughly 28%.
Your everyday glass is made of silica, a sand composed of silicon dioxide, silicon and oxygen.
Quartz is composed of silicon and oxygen.
olivine
Silicon TetrafluorideSi-siliconeF=fluorine4=four
It tells that silicon dioxide is composed of two different elements (Silicon and Oxygen) in a 1 to 2 atomic ratio ( Si1O2 ).
