33. When an atom undergoes gamma decay, the atomic number of the element a. remains the same.
b. decreases by one.
c. increases by one.
d. increases by two.
34. Radioactive materials change into new during radioactive decay.
a. compounds
b. atoms of the same material
c. elements
d. neutrons
35. Nuclear fission is the:
a. Production of uranium.
b. Splitting of protons by bombarding them with neutrons.
c. Splitting of atoms by bombarding them with neutrons.
d. Result of neutrons smashing into each other.
36. During fission:
a. Electrons are released and cause more fission.
b. Protons are released and cause more fission.
c. Uranium is produced.
d. Neutrons are released and cause more fission.
37. Separating U-235 from U-238 was difficult because:
a. There was so much more U-235 than U-238
b. There was so much more U-238 than U-235.
c. A chain reaction would result.
d. They are chemically identical.
Part IV: True/False
38. The mass of the nucleus is small compared to the mass of the atom.
39. Alpha particles would be harder to turn than Beta particles.
40. Positive charge was spread all throughout the atom in the Rutherford Model.
41. The Manhattan Project was located in New York for most of its duration.
42. The cathode rays produced by Thomson were identical for all filaments.
43. It is possible to know where an electron is and what path it is on.
44. X-rays are produced when fast moving electrons strike phosphor coatings.

Because only energy is emitted during gamma decay, the number of protons remains the same. Therefore, an atom does not become a different element during this type of decay. Q: The Figure below shows how helium-3 (He-3) decays by emitting a gamma particle.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
