Atomic History
I. Match the person with what they did. Put the person’s number in the blank.
1. Plato and Aristotle
2. Democritus (460-370 BCE) and his teacher Leucippus
3. Antoine Lavoisier (1743-1794)
4. Joseph Proust (1754-1826)
5. John Dalton (1766-1844)
6. William Crookes (1832-1919)
7. J.J. Thomson (1856-1940)
8. Robert Millikan (1868-1953) (RANDOM - NOT ON TEST)
9. Wilhelm Roentgen (1845-1923)
10. Henri Becquerel (1852-1908)
11. Ernest Rutherford (1871-1937)
12. Hans Geiger (1882-1945)
13. Ernest Marsden (1889-1970)
14. James Chadwick (1891-1972)
____1. Concluded that in a reaction, nothing was created or destroyed - the Law of
Conservation of Mass. Had his head chopped off.
____2. Discovered that there are some substances, like uranium, that give of radiation
spontaneously - no energy had to be applied.
____3. Concluded that the elements in compounds always combined in definite amounts - the
Law of Definite Proportion (also called the Law of Definite Composition). Was burned out by
Napoleon.
____4. Discovered that a beam of electrons shot at an object caused another form of energy to
be emitted from the object. He called this energy x rays.
____5. Put together the Atomic Theory, established the Law of Multiple Proportions, and
explained the difference between a mixture and a compound.
____6. Worked in Rutherford’s lab on the gold foil experiment, an undergraduate student who
worked with Geiger.
____7. Determined the charge then calculated the mass of an electron in his oil drop
experiment.
____8. Worked in Rutherford’s lab on the gold foil experiment, a graduate student who
suggested that Rutherford should let Marsden get some lab experience.
____9. Believed that the world was made of matter that could be divided infinitely.
____10. Figured out that radiation can be divided into alpha particles, beta particles and gamma
rays and that atoms were mostly space with a small, positively charged center by using his gold
foil experiment.
____11. Calculated the existence of a particle the same mass as a proton but with no charge the neutron.
____12. First to get an stream of electrons to pass through a vacuum tube, establishing the
existence of cathode rays.
____13. Is credited with discovering the electron, calculating the electron’s mass to charge ratio,
and creating the plum pudding or blueberry muffin model of the atom.
____14. Said the universe was made of atomos, or small, indivisible particles. Thought these
particles were earth, air, fire, and water.
II. Match the laws with their definition.
A. Law of Conservation of Mass
B. Law of Definite Proportion
C. Law of Multiple Proportions
_____1. You can have different proportions of elements in a compound , but it means
you’ll end up with a different compound each time.
_____2. In a reaction, nothing is created or destroyed; the mass of the reactants before
the reaction is the same as the mass of the product after the reaction.
_____3. Compounds are made of a definite proportions of elements.
