Group VIIIA

A column of the periodic table is called a family. Some families have special names. Group IA elements are called alkali metals, group IIA elements are called alkaline earth metals, group VIIA elements are called halogens, and group VIIIA elements are called the noble gases. The group B elements are called transition elements. Elements with atomic numbers from 58 to 71 are called lanthanides, and elements with atomic numbers from 90 to 103 are called actinides. Families have similar chemical and physical properties. For example, the alkali metals are soft metals at room temperature they are shiny, conduct...

The inner electrons, those below the valence electrons, are arranged as is the noble gas element (Group VIIIA) before the element under consideration. If we were to consider titanium (Ti, Z = 22), the electron configuration could be expressed as [ Ar 13c/24.s2. Note that, although the Aufbau principle indicates the 4s filling before the 3d, it is common practice to present the electron configuration in numerical order with respect to n, rather than the...

The bivalent substitutional impurities of group-IVA elements such as C, Si, Ge, Sn, or Pb also produced double shallow acceptor levels with the ionization energy of 0.721 eV for C, 0.919 eV for Si, 0.792 eV for Ge, 1.034 eV for Sn, and 1.283 eV for Pb, respectively. Some bivalent substitutional impurities of another type of group-VIIIA elements such as Ne, Ar, Kr, or Xe did not produce any energy levels in the band gap by the substituting host O atom. As expected, the acceptor levels produced by the impurities of group-VA and -IVA elements at the O site were single or double acceptors, respectively. Quantitave analysis of these shallow acceptors produced by the monovalent and bivalent substitutional impurities will be made in Section 4.2.
