: The [[Dalton Model]] is a simple [[model]] of the [[atom]] which makes it easier to use the [[Particle Model]] to [[explain]] the [[State of Matter|States of Matter]] and to represent [[molecule]]s.
: The [[Dalton Model]] is not true, but is a useful [[model]] to help describe [[atom]]s.
==Key Stage 4==
===Meaning===
The [[Dalton Model]] is a model of the [[atom]] which shows [[atom]]s as a [[Sphere|spherical]] [[object]].
===About the Dalton Model===
: The [[Dalton Model]] was the first and simplest model of an [[atom]] and was proposed by [[John Dalton]] to explain the fact that [[Chemical Reaction|chemical reactions]] needed specific proportions of [[Reactant|reactants]] to [[Chemical Reaction|react]] completely.
: The existence of the [[atom]] was further backed up by [[Scientific Evidence|evidence]] from [[Brownian Motion]] in which small visible [[particle]]s appear to move randomly because they are being hit by smaller invisible [[particle]]s.
: The [[Dalton Model]] was replaced by the [[Plum Pudding Model]] following the discovery of the [[electron]] by [[J.J. Thompson]].
