: The '''electronvolt''' is denoted with a lower case 'e' followed by an upper case 'V'.
: The '''electronvolt''' is equal to 1.60x10<sup>-19</sup> [[Joule]]s (correct to 3 [[Significant Figures|significant figures]]).
: Since the equation linking [[energy|Energy (E)]], [[Electrical Charge|charge (q)]] and [[Potential Difference|potential difference (V)]] is <math>E=qV</math> then considering the [[Electrical Charge|charge]] on an [[electron]] is [[magnitude]] of the [[Elementary Charge|elementary charge]] and its [[energy]] having been accelerated through a [[Potential Difference|potential difference]] of 1 [[volt]] we can define the [[energy]] of a [[Subatomic Particle|subatomic particle]] in [[integer]]s of the [[Elementary Charge|elementary charge]] <math>E=eV</math> where '''e''' is the magnitude of the [[Elementary Charge|elementary charge]].
