===Meaning===
'''Relative Atomic Charge''' is the [[Electrical Charge|charge]] of a [[particle]] compared to the [[charge]] of a single [[proton]].
===About Relative Atomic Charge===
: [[Ion]]s, [[Atomic Nucleus|nuclei]] and [[Subatomic Particle|subatomic particles]] have extremely small [[Electrical Charge|charge]]s such as the [[proton]] (1.6x10<sup>-19</sup>Coulombs) so instead of stating the [[Electrical Charge|charge]] in [[Coulomb]]s it is compared to the [[Electrical Charge|charge]] of a [[proton]].
