141.gif
  • 92 protons
  • 146 neutrons
  • 238 nucleons
  • 92 electrons
Which one of the following statements about the atomic nucleus is accurate?
  • The nucleus is held together mostly by the electrical and gravitational forces
  • Large nuclei are denser than light nuclei
  • All nuclei have nearly the same density
  • Smaller nuclei are denser than larger nuclei
Nucleus ''a'' contains 5 protons and 5 neutrons and has radius R. The radius of nucleus ''b'', which contains 35 protons and 45 neutrons, is closest to:
  • 2R
  • 8R
  • 1.4R
  • R
Binding energy per nucleon is the ratio of
  • the binding energy of the nucleus to the number of nucleons in that nucleus.
  • energy required to remove a nucleon to atomic weight
  • binding energy of a nucleon to the atomic number
  • binding energy of a nucleus to the atomic number
The atomic number Z of the nucleus is
  • Number of deutrons.
  • Number of neutrons in it.
  • Number if electrons in it.
  • Number of protons in it.
The density of nuclear matter is:
  • independent of the number of nucleons in the nucleus
  • directly proportional to the number of neutrons in the nucleus
  • directly proportional to the number of protons in the nucleus
  • directly proportional to the square of the number of nucleons in the nucleus
The radius of a nucleus is directly proportional to (A=mass number)
  • A1/3
  • A2
  • A3
  • A1/2
The volume of atom in comparison of volume of nucleus is of the order of
  • 1015
  • 105
  • 1025
  • 1030
The average binding energy of nucleus is
  • 8 BeV
  • 8 Mev
  • 8 eV
  • 8 KeV
The number of electrons in an atom X of atomic number Z and mass number A is
  • Zero
  • A
  • Z
  • A-Z
