    the ratio of masses in a pure sample is identical. for elements and molecules
  9. ionic bond
    complete transfer of electrons
  10. polar covalent bonds
    unequal sharing of electrons
  11. nonpoplar covalent bond
    equal sharing of electrons
  12. atomic weight
    average of the relative weights(mass Number) of all isotopes in an element

    Isotope mass X Abundance +total AMU
  13. mass number
    sum of the masses of the isotopes protons and neutron
  14. atomic number
    atomic number of any atom is equal to the number of protons

    H with just one proton and one electron
  16. WHEN DOSE A HYDROGEN BOND FORM
    WHEN A HYDROGEN ATOM ALREADY COVALENTLY LINKED TO ONE ELETRONEGATIVE ATOM IS ATTRACTED BY ANOTHER ELECTRON HUNGRY ATOM (usually nitrogen or oxygen)
  17. how is a molecule formed
    when a combination of 2 or more atoms are held together by chemical bond.
  18. mixtures
    substances composed of two or more components physically mixed
