==Key Stage 4==
===Meaning===
[[File:Hydrogen.png|right|300px|thumb|A image of an [[atom]] in the [[Nuclear Model]] showing a small [[Atomic Nucleus|nucleus]] at the centre and an [[electron]] [[orbit]]ing around the [[Atomic Nucleus|nucleus]].]]
The [[Nuclear Model]] is a model of the [[atom]] which suggests there is a [[Positive Charge|positively charged]] [[Atomic Nucleus|nucleus]] in the centre of an [[atom]] with [[electron]]s [[orbit]]ing around the [[Atomic Nucleus|nucleus]].

===About the Nuclear Model===
: The [[Nuclear Model]] was first proposed by [[Ernest Rutherford]] after he successfully disproved the [[Plum Pudding Model]] of the [[atom]] using his [[Rutherford's Alpha Scattering Experiment|alpha scattering experiment]].
: In the [[Nuclear Model]] most of the [[atom]] is empty space. The majority of the [[mass]] of the [[atom]] is concentrated in a small central [[Atomic Nucleus|nucleus]]. This central [[Atomic Nucleus|nucleus]] has a strong [[Positive Charge|positive charge]] while [[Negative Charge|negatively charged]] [[electron]]s [[orbit]] the [[Atomic Nucleus|nucleus]].
