Introduction,ing units of measurement of physical quantities. In particular, we are very interested here in the units of mass and energy. The units of mass are simple; chemists and, in fact, most scientists use the metric .—or more correctly, as we see in a moment—the .. With energy the common units are more var

Many-electron Atoms,he energy decreases as the square of the atomic number (or charge on the nucleus) increases, and for given atomic number there is an array of energy levels available similar in number to that for hydrogen given in Figure 3.6, but with a different energy scale for each different value of the atomic n

Experimental Methods of Valency,in some cases to provide values of such quantities as dissociation energies. These methods can be divided into two distinct types: (a) . and (b) . methods. Sometimes in the former method diffraction gratings are used to disperse the wavelengths of the radiation used, but the essential difference is
