→Constructing a Feynman Diagram
| style="height:20px; width:200px; text-align:center;" |The [[Subatomic Particle|particles]] prior to the [[Fundamental Interactions|interaction]] are drawn first at the bottom of the '''Feynman diagram'''.
| style="height:20px; width:200px; text-align:center;" |The [[Subatomic Particle|particles]] after the [[Fundamental Interactions|interaction]] are drawn at the top of the '''Feynman diagram'''. It should be recognised that [[Conservation of Baryon Number|baryon conservation]] means a [[baryon]] becomes another [[baryon]] and [[Conservation of Lepton Number|lepton conservation]] means that if a [[lepton]] comes into existence there must also be an [[antilepton]].
| style="height:20px; width:200px; text-align:center;" |Finally the [[boson]] mediating the [[Fundamental Interactions|interaction]] is added as a [[wave]] between the two points of [[Fundamental Interactions|interaction]]. In this case a [[protonneutron]] loses its a [[Positive Negative Charge|positive negative charge]] therefore it is carried away to produce the [[electron]] via the [[W-boson|W<sup>+-</sup> boson]] transforming the [[electron]] into also producing an [[Electron-neutrino|electronantielectron-neutrino]].
