Define enthalpy of atomisation
• energy transferred when 1 mole of the compound is formed from its elements under standard conditions and standard states of all reactants and products.
Define enthalpy of atomisation.
• enthalpy change when 1 mole of GASEOUS atoms is formed from the element in standard states.
Define 1st ionisation enthalpy
• enthalpy change required to remove 1 mole of electrons from 1 mole of gaseous atoms to form one mole of gaseous ion with a 1+ charge.
Define 2nd ionisation enthalpy
enthalpy change required to remove 1 mole of electrons from 1 mole of gaseous atoms to form one mole of gaseous ion of a 1+ to a 2+ charge.
Define first electron affinity
enthalpy chanhe that occurs when 1 mole of gaseous atoms gain 1 mol of electrons to form 1 mol of gaseous atoms with a 1- charge.
