  1. laws of chemical combination
    law of conservation of mass and law of definite proportions
  2. law of conservation of mass
    No detectable gain or loss of mass occurs in chemical reactions. Mass is conserved.
  3. law of definite proportions
    n a given chemical compound, the elements are always combined in the same proportions by mass.
  4. Dalton's Atomic thoery
    1. Matter consists of tiny particles called atoms.

    2. Atoms are indestructible. In chemical reactions, the atoms rearrange but they do not themselves break apart.

    3. In any sample of a pure element, all the atoms are identical in mass and other properties.

    4. The atoms of different elements differ in mass and other properties.

    5. When atoms of different elements combine to form compounds, new and more complex particles form. However, in a given compound the constituent atoms are always present in the same fixed numerical ratio.
  5. Law of multiple porportions
    Whenever two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.
  6. subatomic particles
    protons,neutrons, electrons and atomic nuclei
  7. nucleons
    protons and nuetrons
  8. Atomic number
    number of protons
  9. Isotope
    Atoms of the same element with different atomic masses. Atoms of the same element with different numbers of neutrons in their nuclei
  10. Mass number
    protons + nuetrons
  11. Alkali metals
    The Group IA elements (except hydrogen)—lithium, sodium, potassium, rubidium, cesium, and francium.
  12. Akaline earth metals
    The Group IIA elements—beryllium, magnesium, calcium, strontium, barium, and radium.
  13. Halogens
    Group VIIA in the periodic table—fluorine, chlorine, bromine, iodine, and astatine.
  14. Nitrogen Family
    nitrogen, phosphorus, arsenic, antimony, and bismuth
  15. maleabillity
    A metal's ability to be hammered or rolled into thin sheets
