  1. alpha particle
    a positively charged particle consisting of 2 protons and 2 neutrons.
  2. amphoteric
    an ion molecule that can act as an acid or a base
  3. beta decay
    a nuclear reaction in which an electron or a positron is absorbed by or emitted from the nucleus of an atom
  4. effusion
    the process by which a gas escapes through a pinhole into a region of lower pressure
  5. elastic collision
    a collision in which no kinetic energy is lost
  6. ion product constant of water (Kw)
    1.0*10-14
  7. network solid
    a solid in which every atom is covalently bonded to its nearest neighbors to form an extended array of atoms rather than individual molecules
  8. β- decay
    neutron → proton + electron
  9. β+ decay
    proton → neutron + positron
  10. diamagnetic
    an atom that has all of its electrons spin-paired
