===Meaning===
A [[polymer]] is a large [[molecule]] made of many repeating smaller [[molecule]]s called [[monomer]]s.
===About Polymers===
: [[Polymer]]s are held together by [[Covalent Bond|covalent bonds]].
: The [[monomer]]s which make up a [[polymer]] are [[Simple Covalent Molecule|simple covalent molecules]].
: Most [[polymer]]s are made of chains of [[Carbon]] [[atom]]s as they can from up to 4 [[Covalent Bond|covalent bonds]] with [[adjacent]] [[atom]]s. However, some can be made from [[Silicon]], which can also form 4 [[Covalent Bond|covalent bond]]s.
