Many of the answerers are wrong. Silicone is an artificial (man made) chemical they are thinking of SILICON which is an element. However silicone does contain this element.
Silicone actually refers to a group of chemicals, however they are all made of the same stuff:
RSiO.
R = any of a number of hydrocarbons (oils, natural gas etc)
Si = silicon (found in sand)
O = Oxygen
I hope that helped you, you can see the chemical structure here:

If you are referring to silicones with and E, these are inorganic-organic polymers with the chemical formula [R2SiO]n, where R is an organic group like a methyl, ethyl or phenyl. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common type is linear polydimethylsiloxane or PDMS (a silicone oil). The second largest group of silicone materials is based on silicone resins, which are formed by branched and cage-like oligosiloxanes.
If you are referring to silicon with NO e this is the element silicon with atomic symbol Si and atomic number 14. An element with similar properties is Carbon. In fact, silicon is the only other element on the periodic table that can form complex molecules just like carbon does. On Earth, silicon is the second most abundant element (after oxygen) in the crust, making up 25.7% of the crust by mass. It is a COMPONENT of silicones, a class-name for various synthetic plastic substances made of silicon, oxygen, carbon, and hydrogen. Since the two are named so similarly the two are often confused.
HOPE THIS HELPS YOU!!!

Silicon is an element which is similar to carbon in some of its properties. Silicones are plastics made from silicon instead of carbon.
The fundamental polymer chain is
Si - O - Si - O -Si - O and so on.
with two -OR groups attached to the Si atoms. R may be always methyl, ethyly, phenyl etc or two or three different organic groups. Choice of the R part changes the properties of the polymer. Generally though they are close to incombustible, only charring, and non-adhesive to most other substances.
There is no such thing as a siliconne.

Silicones (more accurately called polymerized siloxanes or polysiloxanes) are inorganic-organic polymers with the chemical formula [R2SiO]n, where R = organic groups such as methyl, ethyl, and phenyl. These materials consist of an inorganic silicon-oxygen backbone (...-Si-O-Si-O-Si-O-...) with organic side groups attached to the silicon atoms, which are four-coordinate. In some cases organic side groups can be used to link two or more of these -Si-O- backbones together. By varying the -Si-O- chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common type is linear polydimethylsiloxane or PDMS (a silicone oil). The second largest group of silicone materials is based on silicone resins, which are formed by branched and cage-like oligosiloxanes.

Note: Silicon is an element, silicone is a compound.
Silicone is made from oxygen, silicon, and hydrocarbons.
