    A subatomic particle that has a neutral charge in an atom
  13. Electrons
    A subatomic particle that has a negative charge in an atom
  14. Atomic number
    Equal to the number of protons Its atom contains
  15. Atomic mass
    The sum of protons and neutrons contained in the atom's nucleus
  16. Atomic weight
    Is equal to the atomic mass
  17. Isotopes
    Different atomic form of the same element. isotopes very and only the number of neutrons they contain
  18. Radioisotopes
    Isotope exhibit radioactive behavior
  19. Radioactivity
    The process of spontaneous decay seen instead of the heavier isotopes during which particles or energy is emitted from the atomic nucleus result in the atoms becoming more stable
  20. Molecules
    When two or more atoms combine
  21. Compound
    Substance composed of two or more different elements the atoms of which are chemically United
  22. Chemical reaction
    Process in which molecules are formed changed, or broken down
  23. Electron shells or energy levels
    The Fixx regions of space around the nucleus
  24. Valence shell
    The outermost energy level of an atom that contains electrons the electrons in the valence shell determine the bonding behavior of the atom
  25. Ionic bonds
    Form when electrons are completely transferred from one atom to another
  26. Ions
    An atom with the positive charge or negative charge
  27. Covalent bonds
    The bond involving the sharing of electrons between atoms.
  28. salt
    Ionic compound that dissociates into charged particles ( other than hydorgen or hydroxyl ions) when dissolved in water
  29. Hydrogen bonds
    Extremely weak bonds formed when a hydrogen bound to one electon-hungry nitrogen or oxygen atom is attracted by another electron-hungry atom
  30. Synthesis reaction
    Occurs when two or more atoms or molecules combine to form a larger more complex molecule.
  31. Decomposition reaction
    Occurs when a molecule is broken down into smaller molecules, atoms, or ions.
  32. Exchange reaction
    Involve both synthesis and decomposition reactions; bonds are both made and broken
  33. Inorganic compounds
    A compound that lacks carbon; for example water
  34. Organic compound

  38. Buffers
    A substance or substances that help to stabilize the ph of a solution
  39. Adenosine diphosphate
    a compound consisting of an adenosine molecule bonded to three phosphate groups, present in all living tissue. The breakage of one phosphate linkage (to form adenosine diphosphate, ADP ) provides energy for physiological processes such as muscular contraction.
