Clues

  • A neutron changes to a proton and an electron. The electron is then emitted. (4, 5)
  • Short wavelength, high energy electromagnetic radiation (5, 5)
  • The actual number of atoms of each element present in a molecule/formula unit of a compound (9, 7)
  • The average mass of one formula unit relative to 1/12th the mass of an atom of C-12 (8, 7, 4)
  • The emission of 2 protons and 2 neutrons (a He nucleus) from an unstable nucleus (5, 5)
  • The mass of an atom compared to 1/12th the mass of an atom of C-12 (8, 8, 4)
  • The number of particles in one mole of a substance: 6.02 x 10(^23) (9, 8)
  • The number of protons in the nucleus of an atom (6, 6)
  • The simplest whole number ratio of atoms of each element present in a compound (9, 7)
  • The total number of protons plus neutrons in the nucleus of an atom (4, 6)
