Abstract
The values of free energies, the heats and entropies of formation and heat capacities of gaseous and condensed atoms of I-VII main and lateral groups and three groups of transitive elements of Mendeleev’s Periodic table were analyzed. Seventy nine equations of such type as ∆g,f,sΨo = i ± f N, in which ∆g,f,sΨo is thermodynamic function, i and f are stoichiometric coefficients, have been calculated. The obtained equations can be used for the calculations of the same functions for other atoms, for with they are not known. The same equations can be used for the next calculation of bond strength in they also. Instead of bond energy (Eb) or bond dissociation energy (BDE) the bond strength (Sb) new symbol of the bond powers for organic and organometallic substances has been suggested. It has been done because there are all thermodynamic functions for practically all atoms of Periodic table and hard to define the bond power with the use the heat function (enthalpy) only; probably is necessary to present the all thermodynamic parameters for the calculating bonds between atoms.
