| Lattice enthalpy | Enthalpy change that accompanies the formation of 1 mole of an ionic compound (solid lattice) from its gaseous ions, under standard conditions |
| Standard enthalpy change of formation | Enthalpy change that takes place when 1 mole of a compound is formed from its (constituent) elements, in their standard states under standard conditions |
| Standard enthalpy change of atomisation | Enthalpy change that takes place when 1 mole of GASEOUS ATOMS forms from the ELEMENT in its standard state |
| 1st ionisation energy (slightly different definition in this context) | Enthalpy change accompanying the removal of 1 electron from each atom in 1 mole of gaseous atoms, to form 1 mole of gaseous 1+ ions |
| 2nd ionisation energy (there can also be 3rd, 4th etc.) | Enthalpy change accompanying the removal of 1 electron from each ion in 1 mole of gaseous 1+ ions, to form 1 mole of gaseous 2+ ions |
| 1st electron affinity | Enthalpy change accompanying the addition of 1 electron to each atom in 1 mole of gaseous atoms, to form 1 mole of gaseous 1- ions |
| 2nd electron affinity | Enthalpy change accompanying the addition of one electron to each ion in 1 mole of gaseous 1- ions, to form 1 mole of gaseous 2- ions |
