Front 1

Define Enthalpy of atomisation

Back 1

The enthalpy change when one mole of gaseous atom is formed from the elements in its standard state

Front 2

Define first electron affinity

Back 2

The enthalpy change that occurs when one mole of gaseous atom gains 1 mole of electrons to form 1 mole of gaseous ion with -1 charge.

Front 3

Define Second electron affinity

Back 3

The enthalpy change when one mole of gaseous 1- ions gains one electron pair ion to produce gaseous 2- ion

Front 4

Define lattice Enthalpy

Back 4

The enthalpy change when 1 mole of an ionic crystal lattice is formed from its constituent ions in gaseous form

Front 5

Define enthalpy of hydration.

Back 5

Enthalpy change when one mole of gaseous ions becomes aqueous ions

Front 6

Define Enthalpy of solution

Back 6

The enthalpy change when one mole of an ionic solid dissolves in a large enough amounts of water to ensure that the dissolved ions are well separated and don't interact when one another.

Front 7

Define First ionisation energy

Back 7

The enthalpy change required to remove one mole of electrons from one mole if gaseous atom to form 1 mole of gaseous +1 ion.

Front 8

Define second Ionisation energy

Back 8

The enthalpy change required to remove one mole of electrons from one mole if gaseous +1 ion to form 1 mole of gaseous +2 ion
