Subatomic particles are particles that are smaller than atoms and are the building blocks of matter. They include particles with both mass and electric charge, as well as particles with no mass and no electric charge. Here are some of the main subatomic particles: 1. Protons: Protons are positively charged particles found in the nucleus of an atom. They have a relative mass of 1 and a charge of +1. Protons are composed of quarks, specifically two up quarks and one down quark. 2. Neutrons: Neutrons are particles found in the nucleus of an atom, alongside protons. Neutrons have a relative mass of 1 and no electric charge. They are also composed of quarks, with one up quark and two down quarks. 3. Electrons: Electrons are negatively charged particles that orbit the nucleus of an atom. They have a relative mass of about 1/1836 (significantly smaller than a proton or neutron). Electrons are fundamental particles and do not consist of smaller particles. 4. Quarks: Quarks are elementary parti...
