Enthalpy of Formation
The enthalpy change when 1 mole of a compound is formed from it's elements in their standard states under standard conditions
1 of 8
Ionisation Enthalpy
The enthalpy change when 1 mole of gaseous +1 ions are formed from 1 moles of gaseous atoms under standard conditions (can also be used to form 2+ ions from 1+ ions through the loss of a second electron)
2 of 8
Enthalpy of Atomisation
The enthalpy change when 1 moles of gaseous atoms is formed from the elements in their standard states

Bond Dissociation Enthalpy
The enthalpy change when all the bonds of the same type in 1 mole of gaseous molecules are broken
4 of 8
Electron Affinity
The enthalpy change when 1 mole of gaseous 1- ions are formed from 1 mole of gaseous atoms
