The elements are found in various states of matter and define the independent
constituents of atoms, ions, simple substances, and compounds. Isotopes with the same
atomic number belong to the same element. When the elements are classified into groups
according to the similarity of their properties as atoms or compounds, the periodic table
of the elements emerges. Chemistry has accomplished rapid progress in understanding
the properties of all of the elements. The periodic table has played a major role in the
discovery of new substances, as well as in the classification and arrangement of our
accumulated chemical knowledge. The periodic table of the elements is the greatest table
in chemistry and holds the key to the development of material science. Inorganic
compounds are classified into molecular compounds and solid-state compounds
according to the types of atomic arrangements.
