Polymers
A large molecule formed from many identical smaller molecules known as monomers. have very large A collection of two or more atoms held together by chemical bonds.. The atoms in a polymer molecule are joined together by strong A bond between atoms formed when atoms share electrons to achieve a full outer shell of electrons. in long chains. There are variable numbers of atoms in the chains of a given polymer. One example of a polymer is poly(ethene).
A short section of a poly(ethene) molecule. Poly(ethene) molecules contain thousands of carbon atoms joined together in a chain
This diagram also represents poly(ethene). The value of 'n' varies, but it is always a large number
