We note that the valence orbitals of metal atoms order in energy as AE>Ln>M. The d-levels of transition elements (M) range the lowest, and are therefore most sensitive for reduction, or to form a stable binary metal nitride. This may also explain the virtual absence of d-element compounds with 16 (valence) electron species, such as [N=N=N] , [N=C=N] , [N=B=N] T [C=C=CfT or [C=B=C] T at least through high-temperature syntheses. 

D Element losing electrons is oxidized, element gaining electrons is reduced. 

In our previous survey (7) of the hexafluoro complexes of the 3d series we discussed in some detail the information which may be derived from a consideration of the value of the nephelauxetic ratio, / (=i compiex/5gas). To obtain this parameter it is clearly necessary to have available values of the free-ion Racah parameter, B, and for the 4 d elements these may be obtained either from the compilation of Di Sifiio et al. (75) or by use of the Jorgensen-Racah relationship (76, 77). 

Note Where the 5d values are derived from 3d results based on empirical Slater-Condon parameters, the same caveat applies as for the 4 d elements. [C. f. also Ref. (7)]. 

According to Girgis (1983) the existence field of the electron phases may be especially related to the combinations of d elements with the elements of the Periodic Table columns from 11 to 14 (from the Cu to Si groups). It can also be observed that, for several alloy systems, the dependence of the structures (structure types) on the electron concentration (instead of on the composition) may be clearly illustrated by well-known diagrams such as those shown in Fig. 4.39.

Our laboratory started to work on circadian rhythms by serendipity, while studying the liver-specific transcription of the serum albumin gene. We isolated a cDN A copy for a transcription factor that we dubbed DBP (for albumin promoter D-element Binding Protein). DBP, a basic leucine zipper (bZip) transcription factor, is the founding member of the PAR (proline-acidic amino acid rich)-domain bZip transcription factors, a small subfamily of bZip proteins consisting of DBP, TEF and HLF. It turned out that DBP protein and mRNA accumulation undergo circadian cycles with amplitudes in excess of one hundred-fold (Wuarin Schibler 1990).
