===About Atoms in The Dalton Model===
: In [[The Dalton Model]] [[atom]]s are shown as [[sphere|ball]] shaped [[particle]]s. This makes it easier to draw [[diagram]]s of [[molecule]]s.

===About Atoms beyond The Dalton Model===
: [[Atom]]s are 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 [[orbiting]] the [[nucleus]] in 'shells'.

: In an [[atom]] the number of [[proton]]s is always the same as the number of [[electron]]s.
: Different [[atom]]s can have different numbers of [[proton]]s and [[neutron]]s.
: The simplest [[atom]] is [[Hydrogen]] which has 1 [[proton]] and 1 [[electron]] and no [[neutron]]s.
