Abstract

The strengths of H-X bond (Sb) of lithium,  sodium, beryllium, magnesium, calcium, carbon, silicon, nitrogen, phosphorus, arsenic, oxygen and sulfur were calculated with use of equation ∆aΨogas/cond  = Σ ∆atomΨogas/cond - ∆fΨogas/cond  = Σ Sb gas/cond, in which were included the functions of free energy and the heats of formation in gaseous and condensed phases. The calculated bond energies of hydrides represent from itself the small magnitudes in a condensed state relatively to the same values in the gaseous phase. One of the reasons it is a small magnitude of the formation of chosen atoms and the formed from they hydrides in a condensed state.

Keywords:
Hydride, free energy, the heat of vaporization, the heat of formation, the strength of the bond
