For the special case of the formation of a compound from the elements, the change is designated ΔH form and is a weak function of temperature. Values of ΔH form are usually given where the elements and compound are in their normal standard states, and as such are designated standard heats of formation, as
A given reaction is considered as the decomposition of all reactants into elements in their standard states, followed by the formation of all products. The heat of reaction is then minus the sum of the standard enthalpies of formation of the reactants (each being multiplied by its respective stoichiometric coefficient, ν) plus the sum of the ...

This Table, reports the three main Miedema parameters for the elements of the Periodic table for whom the model is applicable. These are original parameters [13] which are after page 24 of the book after F.R. De Boer, R. Boom, W.C.M. Mattens, A.R. Miedema and A.K. Niessen Cohesion in Metals. Transition Metal Alloys (1988), [14]

Standard enthalpy of formation is the enthalpy change when one mole of any compound is formed from its constituent elements in their standard states. The enthalpy of formation of one mole of ethane gas refers to the reaction 2 C (graphite) + 3 H 2 (g) → C 2 H 6 (g).
