  3. affinity: The change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
  4. gases: Any of the gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 0 (18) of the periodic table. They were long believed to be totally unreactive but compounds of xenon, krypton, and radon are now known. All noble gases have full valance orbitals.
  5. elements: All elements in the s and p blocks of the periodic table. The most abundant elements in the periodic table.
  6. configuration: A simplified version of electron configuration.

  8. Any chemical element that is an effective conductor of electricity and heat can be defined as a metal. A metal is also good at forming bonds and cations with non-metals. Atoms inside of a metal quickly lose electrons in order to make positive ions or cations. The ions in turn are surrounded by the electrons that are delocalized, which give the metal its electric conductivity.
