The line spectra of a number of gases. Each spectrum is unique and alloujs the identification of the elements. From top to bottom, the spectra represent bromine, deuterium, helium, hydrogen, krypton, mercury, neon, water vapor, and xenon.

Once we came to believe in atoms, it was logical to ask What is the nature of an atom Does an atom have parts, and if so, what are they In Chapter 2 we considered some of the experiments most important for shedding light on the nature of the atom. Now we will see how the atomic theory has evolved to its present state. 

One of the most striking things about the chemistry of the elements is the periodic repetition of properties. There are several groups of elements that show great similarities in chemical behavior. As we saw in Chapter 2, these similarities led to the development of the periodic table of the elements. In this chapter we will see that the modern theory of atomic structure accounts for periodicity In terms of the electron arrangements in atoms.

J. Barrett, Atomic Structure and Periodicity, Royal Society of Chemistry, Cambridge, 2001. This book is meant to act as preliminary reading for the present text, but covers the subject matter in a largely non-mathematical way. The theoretical basis of the Periodic Table is dealt with in considerable detail and is followed by discussions of the periodicities of the main physical and chemical properties of the elements.
