( Figure 1.24 'The Periodic Table Showing the Elements in Order of Increasing ' also see Chapter 32 'Appendix H: Periodic Table of Elements'), We will explain the rationale for the peculiar format of the periodic table in Chapter 7 'The Periodic Table and Periodic Trends'.

The known elements are arranged in order of increasing Z in the periodic table A chart of the chemical elements arranged in rows of increasing atomic number so that the elements in each column (group) have similar chemical properties. The atomic number is therefore different for each element. The identity of an element is defined by its atomic number ( Z) The number of protons in the nucleus of an atom of an element., the number of protons in the nucleus of an atom of the element. Rutherford’s nuclear model of the atom helped explain why atoms of different elements exhibit different chemical behavior. To know the meaning of isotopes and atomic masses.
