Valence energies, relation

In the case of metal forming two cations, M and Jf, there will coexist the equilibria of three systems MIM, MjM and M jM with corresponding oxidation potentials e", s,sr s", or reduction potentials 7t , 7t° and tc",2. Lot us assume that tho ion Mz, has a higher valency than M (Z2 > Zj). The standard free energies related to individual respective processes are thus ... 

How is the energy level of an atom s valence electrons related to the period it is in on the periodic table (6.2)... 

Zahradnlk et al.160 have combined a set of parameters which may be regarded as aromaticity indices into the stability index. The approach is more comprehensive than that of Balaban, but as the authors point out it is obviously difficult to assess the relative importance of the selected indices. Those included are the specific delocalization energy DE,P34 (Section II, A,3,a) related to the extent of -electron delocalization, Aq the difference between the maximum and minimum ir-electron density in the molecule (related to the reactivity toward nucleophilic and electrophilic reagents see the preceding section), the free valence F (related to radical reactivity) and the radical super-delocalizability ST (related to radical reactivity, oxidizability, and reducibility). 

Summarize the general trend in ionization energy. How does ionization energy relate to the number of valence electrons in an element ... 

Table 7 Bond energies related to oxidative addition reactions and energy of valence orbital...

In the second step of the chemical-bonding analysis the space O of the states of aU the valence energy bands is projected on the spaces f of IR of the site-symmetry groups related to the components of the BR in the q-basis established above. 

We will also learn that electrons are arranged in different energy levels within atoms. The electrons in the highest energy level, called valence electrons, relate groups of elements and determine similarities in their physical and chemical behavior.
