Since silicone is not an element, it is not found on the Periodic Table, or does it have such an abbreviation. Silicone is known by most people as what seals (and bonds) the glass joins of aquaria (fish tanks), sealing door and window frames, as sealant in kitchens and bathrooms, and in more recent years, products such as oven-mitts/pot-holders, utensils, ice-cube-trays... Well, it's a very versatile and widely used compound.

Silicon on the other hand, which is what you are meaning, is abbreviated as Si on the Periodic Table of Elements, and is a shiny metal.

The important clarification here is that silicon is the element, and silicone is the rubber-like polymer. The two words are not interchangeable, and are the names of two very different things.
On an interesting side-note, silicon is one of the several elements/atoms that make up the molecule of silicone.
Silicone: The flexible rubber-like material. A compoundof numerous elements.
Silicon: The metal, the element, the atom. A metalloid.
Yes, this misinformation, the misuse of the terms is very common, and for some reason, product labelling, educational television programs, teachers, and so on, are just as likely to misuse the terms. But common does not imply correct.
Lastly, of course it's very understandable for the average person to be misinformed when even those we look up to as experts carelessly abuse the terms.
