Abstract

The relationship between bond energy E AB and stability of covalence compounds bave been studied,according to the method of calculating bond energy.The results show that the bond which bond energy E AB is less than 2.5 eV is not stable and the bond which E AB is greater than 7 eV is very stable,by semiempirical IEHM calculation.Then,the stability of covalence compounds can be inferred from bond energy E AB .
