Lattice enthalpy definitions

Pregunta	Respuesta
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
