  "id": "MLC-T-CHM-001156",
  "term": "Β-decay",
  "field": "Chemistry",
  "definition": "A type of radioactive decay in which a beta particle (an electron or a positron) is emitted from an atomic nucleus. This process involves the transformation of a neutron into a proton (β⁻ decay) or a proton into a neutron (β⁺ decay), accompanied by the emission of an antineutrino or a neutrino, respectively. Beta decay changes the atomic number of the nucleus while keeping the mass number constant, leading to the formation of a new element.",
