Q:

What elements are in plastic?

A:

Quick Answer

Plastics are comprised of a combination of elements such as carbon, silicon, nitrogen, oxygen, sulfur, chlorine and hydrogen. Carbon atoms form the backbone of most plastics, except the silicones, which have silicon as their base element. Plastics are polymers.

Full Answer

Plastics generally consist of molecules made up thousands of atoms bound to each other. As a result, most plastics have a high molecular weight. In carbon-based plastics, each carbon atom can join with other atoms and create up to four chemical bonds. These can result in long chains, forming a thermoplastic. Examples of plastics in general use include the packaging of cleaning products, car bumpers and the packaging of food products, such as ketchup.

    What are organic compounds made of?

    A:

    Organic compounds contain carbon, and almost all organic compounds contain hydrogen, with many also comprised of additional atoms of nitrogen, oxygen or sulfur. Not all compounds that contain carbon, however, can be considered organic. Metallic alloys that contain carbon, such as steel for example, would not be universally considered organic, mainly because they are not involved in biological processes.

    What elements are found in lipids?

    A:

    Every type of lipid contains oxygen, hydrogen and carbon, but a specific type known as a phospholipid also contains phosphate and nitrogen. All of the lipids are considered organic compounds due to the presence of carbon, and they are insoluble in water. The varying structure of lipid molecules results in their different types.
