The diameter of a mercury atom, atomic number 80, compared with the diameter of a zirconium atom, atomic number 40, is approximately
 
  1) half as large
  2) twice as large
  3) the same size
 
  because the
  4) atomic masses are not appreciably different.
  5) greater nuclear charge pulls the orbiting electrons closer.
  6) atomic number and atomic diameter are directly proportional to each other.
  7) atomic number and atomic diameter are inversely proportional to each other.

Question 2

Orbital electrons do not spiral into the atomic nucleus because of
 
  1) electrical forces,
  2) the wave nature of the electrons,
  3) angular momentum,
  4) the discreteness of energy levels,
  5) quantum mechanical laws,
 
  and the electrons have discrete radii from the nucleus because
  6) the circumference of each orbit is an integral multiple of the electron wavelength.
  7) electrical forces act over discrete distances.
  8) energy levels themselves are discrete.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
