==Key Stage 4==
===Meaning===
'''Atomic structure''' is what an [[atom]] is made of and how those parts are arranged.
===About the Atomic Structure===
: The '''atomic structure''' was not always known and has gone through several advances; The [[Dalton Model]] the [[Plumb Pudding Model]] the [[Nuclear Model]] and the [[Bohr Model]].
: [[Atom]]s are now known to be made of three smaller [[particle]]s; the [[proton]], [[neutron]] and [[electron]].
: [[Proton]]s and [[neutron]]s are found in the [[nucleus]] at the centre of an [[atom]]. [[Electron]]s are found [[Electron Orbital|orbiting]] the [[nucleus]] in 'shells'.

===The Subatomic Particles===
: The [[proton]]s and [[neutron]]s are known as [[nucleon]]s because they are found in the [[Atomic Nucleus|nucleus]]. The [[electron]]s are not part of the [[Atomic Nucleus|nucleus]] so they are not [[nucleon]]s.
: These [[particle]]s all have slightly different properties. Since the [[Subatomic Particle|subatomic particle]]s are so small their [[mass]] and [[charge]] are extremely small numbers so, to make it easier, they are represented as 'relative' [[mass]] and 'relative' [[charge]] compared to a [[proton]].
