Ionisation enthalpy | first ionisation energy is the enthalpy change when one mole of gaseous atoms loses one electron per atom to produce gaseous 1+ ions |
Electron affinity | the first electron affinity is the enthalpy change when one mole of gaseous atoms gains one electron per atom to produce gaseous 1- atoms |
enthalpy of atomisation | enthalpy change when one mole of gaseous atoms is produced from an element in its normal state |
hydration enthalpy | enthalpy change when one mole of gaseous ions became hydrated (dissolved in water) forming one mole of aq ions |
Enthalpy of solution | enthalpy change when one mole of ionic solid dissolves in an amount of water large enought that the dissolved ions are well separated and do not interact with each other |
