Enthalpy of atomization is the amount of enthalpy change when bonds of the compound are broken and the component atoms are separated into single atoms ( or monoatom). Enthalpy of atomization is denoted by the symbol ΔH at. The enthalpy change of atomization of gaseous H 2 O is, for example, the sum of the HO–H and H–OH bond dissociation ...
Enthalpy of atomization - is defined as the enthalpy change required to separate one mole of a substance into its constituent atoms completely. Enthalpy of neutralization - is defined as the enthalpy change observed in a constituent of a thermodynamic system when one mole of water is formed when an acid and a base react.
may be considered as the sum of several steps, each with its own enthalpy (or energy, approximately): H sub, the standard enthalpy of atomization (or sublimation) of solid lithium. IE Li, the first ionization energy of gaseous lithium. B(F–F), the standard enthalpy of atomization (or bond energy) of fluorine gas.
Temperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone. In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.

Remove from heat, add chocolate, and stir with a rubber spatula until melted and smooth. Stir in vanilla, espresso powder, and salt. In a large bowl, whisk granulated sugar and brown sugar.
The enthalpy of formation of lithium fluoride (LiF) from its elements in their standard states (Li(s) and F 2 (g)) is modeled in five steps in the diagram: Atomization enthalpy of lithium; Ionization enthalpy of lithium; Atomization enthalpy of fluorine; Electron affinity of fluorine; Lattice enthalpy
