  • Group zero elements are non-metals found in the last column of the periodic table.
  • Group zero elements are called noble gases.
  • Noble gases are unreactive or inert.
  • Argon is used in filament bulbs due to its non-reactivity.
  • Noble gases have full outer shells, making them stable and unreactive.
  • Helium has two electrons in its outer shell, while other noble gases have eight.
  • Noble gases exist as single atoms, not molecules.
  • Relative atomic mass increases down group zero.
  • Boiling points of noble gases increase down the group.
  • Larger mass and size of atoms result in stronger intermolecular forces, requiring more energy to overcome.
  • The further down the group, the higher the relative atomic mass, melting, and boiling points.
  • Properties can be predicted from trends down a group.
  • Boiling points can be estimated by observing trends, such as a 30 to 50-degree increase between elements.
