  • B particles = Fast moving electrons (Negitiviely charged -)
  • Y rays = High energy electromagnetic radiation (No charge)
  • When an element emitts an alpha particle its mass number decreases by 4 and its atomic number decreases by 2 (2+2=4) (2+0=2) 2 places to the left
  • When an element emitts a beta particle its mass number is
