Following what already exposed in "The statistical origin of the Alpha constant2", a model based purely on statistical mechanics is proposed to explain and calculate with high accuracy the properties of the electron, likecharge, spin and magnetic moment. All these features, beyond the very existence of the electromagnetic interaction, derive essentially from the assumption that a boson wave field possesses a chemical potential and from the definition of two statistical sets of opposite temperature. It's also shown that the SU(2) algebra, which is normally just assumed for the half Spin particles, is a consequence of this statistical structure, as it happens for theelectric interaction. The only constants used are c, ħ and the Boltzmann constant. The model predicts also a light asymmetry between electric repulsion and attraction that could explain the origin of the weak interaction.
