Enthalpies of Bond: Atomisation, Sublimation, Phase Transition

WebJul 10, 2024 · Most compounds of transition metals are paramagnetic, whereas virtually all compounds of the p-block elements are diamagnetic. The electronegativities of the first-row transition metals increase smoothly from Sc (χ = 1.4) to Cu (χ = 1.9). Thus Sc is a rather active metal, whereas Cu is much less reactive. WebAtomisation enthalpy is represented by the Ha symbol. Dihydrogen is a diatomic cell, and a certain amount of energy is required to break its bond and release the individual atoms as gas. The outcome is that the atomisation enthalpy has always been positive. Heat Dissociation Enthalpy is another name for atomisation temperature in the case of H2.
