Electrons are a type of fundamental particle known as a Lepton. Protons how ever are made up of quarks. A proton has a quark structure of up, up, down (UUD). The up quark has a charge of +2/3 and the down has -1/3 which gives the proton its overall positive charge. The up and down quark both have a strangeness value of 0 and also make up nearly all of the matter which is common on earth including neurons which have a quark composition of UDD.
