| Question | Answer |
| Enthalpy of hydration | Enthalpy change when 1 mole of gaseous ions forms aqueous ions |
| Lattice enthalpy of dissociation | Enthalpy change when 1 mole of an ionic compound is separated into it's gaseous ions |
| Lattice enthalpy of formation | Enthalpy change to form 1 mole of an ionic substance from it's gaseous ions |
| Mean bond dissociation enthalpy | The average enthalpy change to break the bond(s) in one mole of a substance/ molecules of a substance to form its gaseous atoms |
| Electron affinity | Enthalpy change when 1 mole of gaseous atoms forms 1 mole of gaseous negative ions |
| Enthalpy of atomisation | enthalpy change when 1 mole of gaseous atoms is formed from the element in it's standard state |
| Perfect ionic model | Ions are perfect spheres and the compound contains only electrostatic forces of attraction |
| Enthalpy of formation | Enthalpy change when 1 mole of a substance is formed from it's elements and all reactants and products are in their standard state |
| Enthalpy of solution | Enthalpy change when one mole of a compound/ substance forms it's aqueous ions |
| Ionisation enthalpy | Enthalpy change when 1 mole of gaseous atoms is forms 1 mole of gaseous positive ions |
