By xantheWho Would Like To Be A Millionaire. Mike Mills Paul Hopkins. Important Terms. Ionization - The energy required to remove an electron from an individual atom during the gas phase Electronegativity- The relative ability of an atom in a molecule to attract shared electrons to itself
By perryHistory of the Periodic Table. Russian scientist Mendeleev determined that when atoms are arranged in order of increasing atomic mass chemical properties appeared at regular intervals.
By judePeriodic Trends and Z eff. Role of core electron shielding in atomic properties. Atomic Radius. Atomic radius is defined as half the distance between neighboring atoms Covalent Radius is half the distance between two bonded atoms
By abdul-gainesPeriodic Variation in Physical Properties. Sizes of atoms and ions Ionization energy Electron affinity Metallic properties. Properties and Electronic Structure. Properties depend on. valence electrons. Effective nuclear charge (net charge on an electron)
By chanda-kimChapter 6. The Periodic Table. The Periodic Table. Development of the Periodic Table: About 70 elements were discovered before the 1880s Dmitri Mendeleev first listed elements in a systematic, organized way. He arranged atoms by their properties and in order of atomic mass.
