==Key Stage 4==
===Meaning===
[[File:AtomDiagram.png|right|300px|thumb|A [[diagram]] of an [[atom]] showing the '''nucleus'''.]]
The '''nucleus''' is the centre of an [[atom]] containing [[proton]]s and [[neutron]]s.
===About the Nucleus===
: The '''nucleus''' was discovered by [[Ernest Rutherford|Rutherford]] in his [[Rutherford's Alpha Scattering Experiment|alpha scattering experiment]].
: 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) while the [[atom]] ranges 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).
