It is a means of calculating the strength of a chemical bond. In diatomic molecules specifically, it is equal to the value of bond energy. The bond between silicon and fluorine is said to have the strongest bond dissociation enthalpy.

The chalcogens are the elements in column 16 (or group VI A in the old notation) of the periodic table of elements : oxygen, sulphur, selenium, tellurium and polonium. Their outer shell has a deficit of two electrons, hence their propensity to form two bonds or a double bond, for example in the molecule H 2 O and the CO group (in the acidic ...

Tellurite=chalcogen. Definition. Tellurium and its oxyanions are highly toxic. Bacteria have developed resistance mechanisms to overcome the tellurium and tellurite toxic effects.
