Input (English): The electron dipole moment of this particle is at most three times ten to the negative 26th, and would violate CPT-symmetry if it is non-zero. This particle has a half-life of 881 seconds, and can break up into a proton, an electron and an electron antineutrino via beta decay. This particle is composed of one (*) up and two down quarks, and nuclear fission is initiated by the bombardment of this particle. The number of this particle dictates what isotope an atom is, and they have mass roughly equal to that of a proton. James Chadwick discovered, for ten points, what particle found in the nucleus, which, as its name suggests, has a net charge of zero
