The elements are found in various state of matter and define the independent state of constituents of atoms, ions and simple substances and compounds. Isotopes with the same atomic number belong to the same elements. When elements are classified into groups according to the similarities of their properties as atoms or compounds the periodic table of the elements emerges.
