definition of lattice enthalpy
a measure of the strength of ionic bonding in a giant ionic lattice
enthalpy change that accompanies formation of one mole of an ionic compound from its gaseous ions under standard conditions
definition of standard enthalpy change of formation
enthalpy change that takes place when one mole of a compound is formed from its elements under standard conditions
definition of standard enthalpy change of atomisation
enthalpy change that takes place for the formation of one mole of gaseous atoms from the element in its standard state under standard conditions
definition of first ionisation energy
enthalpy change required to remove one electron from each atom in one mole of gaseous atoms to form one mole of gaseous 1+ ions
definition of first electron affinity
enthalpy change that takes place when one electron is added to each atom in one mole of gaseous atoms to form one mole of gaseous 1- ions
definition of second electron affinity
enthalpy change that takes place when one electron is added to each ion in one mole of gaseous ions to form one mole of gaseous 2- ions
