Chemistry students are increasingly fed a diet of orbitals, electronic configurations, and other theoretical concepts instead of being exposed to the more tangible colors, smells, and even explosions of real chemistry. Some authors advocate making chemical education more chemical while at the same time introducing students to the necessary concepts in modern physics. In such an endeavor, the periodic table can serve as an excellent link between macroscopic chemical properties and the underlying quantum mechanical explanations. 

Using Table 1-4, work out the terms arising from the orbital electronic configuration and designate the most stable... 

Uranium is the fourth element of the actinide (SJ series. In the actinide series the electrons are more effectively shielded by the Is and 7p electrons relative to the 4f electrons (shielded by 6s, 6p) in the lanthanide (4p series. Thus, there is a greater spatial extension of 5f orbitals for actinides than 4f orbitals for lanthanides. This results in a small energy difference between and 5/ 6d7s electronic configurations, and a wider range of oxidation states is...

Like palladium(II) and platinum(II), gold(III) has the d8 electronic configuration and is, therefore, expected to form square planar complexes. The d-orbital sequence for complexes like AuC14 is dx2 yi dxy > dvz, dxz > dzi in practice in a complex, most of these will have some ligand character.

Write the shorthand electron configuration and draw the ground-state orbital energy level diagram for the valence electrons in a sulfur atom. 

For the pyrimidines a range of the binding modes offers the possibility for metal-metal interactions (Fig. 24). Many of these combinations have been confirmed by X-ray crystallography, and a discussion of metal metal interactions has been presented (79). The extent of interaction appears to be dependent on both the electronic configuration and the geometry of the metal. Short intermetallic separations (Pt-Pd = 2.49 A) are observed for f raws-Pt(amine)2 derivatives, particularly those in which the filled Pt dz2 orbital can donate electron density into the heterometal dx2 v2 orbital (Fig. 25) (80). 

Let s look at the ground state electron configuration and orbital diagram of the beryllium atom (4Be) which is the first element in group 2A.
