: [[Atom]]s consist of a small, central [[Atomic Nucleus|nucleus]] containing [[proton]]s and [[neutron]]s surrounded by [[electron]]s [[Electron Orbital|orbiting]] the [[Atomic Nucleus|nucleus]].
: The [[electron]]s [[orbit]] the [[Atomic Nucleus|nucleus]] in so called '[[Electron Orbital|electron shells]].
: [[Atom]]s range in size from a [[diameter]] of around 1x10<sup>-10</sup>[[m]] (0.1[[nanometre]]s) to 5x10<sup>-10</sup>[[m]] (0.5[[nanometre]]s), while the [[Atomic Nucleus|nucleus]] has a [[diameter]] of around 1.75x10<sup>-15</sup>[[m]] (1.75[[femtometre]]s to 15x10<sup>-15</sup>[[m]] (15[[femotmetre]]s).: Since [[molecule]]s are made of multiple [[atom]]s they can range from 0.2[[nanometre]]s to several [[millimetre]]s long for long [[polymer]] chains.
