1 of 9
enthalpy of atomisation
the enthalpy change which accompanies the formation of one mole of gaseous atoms from the element in its standard state under standard conditions
2 of 9
first ionisation energy (first IE)
the standard enthalpy change when one mole of gaseous atoms is converted to a mole of gaseous ions each with a single positive charge
3 of 9
first electron affinity
the standard enthalpy change when a mole of gaseous atoms is converted to a mole of gaseous ions, each with a single negative charge
4 of 9
second electron affinity
the enthalpy change when a mole of electrons is added to a mole of gaseous ions each with a single negative charge to form ions each with two negative charges
