==Key Stage 5==
===Meaning===
An '''electronvolt''' ('''eV''') is a [[unit]] of [[energy]] defined as the [[energy]] required to accelerate an [[electron]] across a [[Potential Difference|potential difference]] of one [[volt]].

===About the Electronvolt===
: 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]]).
