WebOnly two types of quark are necessary to build protons and neutrons, the constituents of atomic nuclei. These are the up quark, with a charge of + 2/ 3e, and the down quark, which has a charge of − 1/ 3e. The proton consists of two up quarks and one down quark, which gives it a total charge of + e.

WebOnly two of these – the electron and the photon – would have been familiar to anyone 100 years ago. They are split into two groups: the fermions and the bosons. The fermions are the building blocks of matter. There are 12 fermions, split into six quarks and six leptons. Of the familiar particles that make up the atom, the electron is a lepton. portchester bridge club

They result from the radioactive decay of heavy elements such as radium, thorium, uranium, and plutonium. Because of their double-positive charge, α particles have great ionizing power, but their large mass ...
