Carbon and hydrogen. Many kinds of plastics, such as pure natural rubber (polyisoprene), polyethylene, polystyrene, polypropylene, etc., are composed entirely of carbon and hydrogen. Plastics are essentially long chains of carbon and hydrogen with other elements on occasion -- e.g. chlorine in polyvinyl chloride, nitrogen and oxygen in nylon, fluorine in Teflon, etc.

Hydrogen and carbon.
A binary compound.
All the transition elements are metals. In the usual wide form periodic table, the transition elements are in columns 3 - 12 and in two rows at the bottom of the main table. Those in the rows at the bottom are also called "inner transition elements".
Elements do not contain chemical, but chemicals contain elements. Elements are singular things with a set of properties all their own. There are currently 118 different known elements. Chemicals, which there are thousands of, are made up of two or more elements. Na is sodium(poisonous) and Cl is chlorine(also poisonous). When these two elements combine, you get NACl, which is table salt(not poisonous) and has properties completely different than the two individual elements.
Oxygen contain oxygen atoms and silicon contain silicon atoms.
By properties they are Thermosetting plastics and Thermoplastics
(Cu4O2) contain two elements: copper and oxygen.
thermosettings and thermoplastics. A thermoplastic can be remelted and reused, a thermoset cannot.

A molecule contain two or more chemical elements.
A compound with the chemical formula H2SO is not known. Water (H2O) contain two elements. Sulfurous acid (H2SO3) contain three elements. ...etc.
Two sets are equal if they both contain the same elements.
The main elements of lpg are, butane , methane(CH4) and etyl mercaptan.
