Lattice energy

What is Lattice Energy?

• one mole of an ionic compound is formed from its gaseous ions under standard conditions

• one mole of electrons is added to one mole of gaseous atoms to form one mole of gaseous 1- ions under standard conditions

• one mole of an ionic compound is formed from its atoms under standard conditions

• one mole of gaseous atoms is formed from its element under standard conditions
