Vocabulary Report

  • atomic radius -

    one-half of the distance between the center of identical atoms that are not bonded together

  • alkali metals -

    one of the elements of Group 1 of the periodic table

  • alkaline earth metals -

    one of the elements of Group 2 of the periodic table

  • effective nuclear charge -

    the amount of positive charge that an electron in an atom experiences, taking into account the shielding effect of other electrons in the atom

  • electron affinity -

    the energy needed to remove an electron from an atom

  • ionization energy -

    the energy required to remove an electron from an atom or ion

  • halogens -

    one of the elements of Group 17; halogens combine with most metals to form salts

  • periodic law -

    the law that states that the repeating chemical and physical properties of elements change periodically with the atomic numbers of the elements

  • lanthanide/actinide series -

    a member of the actinide/lanthanide rare-earth series

  • metalloids -

    an element that has properties of both metals and nonmetals sometimes referred to as a semiconductor

  • noble gases -

    one of the elements of Group 18 of the periodic table; noble gases are unreactive

  • transition metals -

    one of the metals that can use the inner shell before using the outer shell to bond

  • period -

    a horizontal row of elements in the periodic table

  • Mendeleev -

    Russian chemist who developed a periodic table of the chemical elements and predicted the discovery of several new elements

  • Moseley -

    an English physicist whose main contributions to science were the quantitative justification of the previously empirical concept of atomic number

  • periodic groups -

    also known as a family; a vertical column in the periodic table of the elements that share similar chemical properties
