WHAT IS LATTICE ENERGY

WHAT IS LATTICE ENERGY

Amount of energy released when one of the crystal lattices is from, it is represented by u

OR

one mole anion and one-mole cation from the energy released    is called lattice energy 

factor affecting of lattice energy 

1) lattice energy increases the size of cation  decreases2) In down the g.p. lattice energy decreases

3)NaCl,,, MgCl2,,,, AlCl3,,,  size of cation decreases lattice energy increase Na+,,, Mg2+,,, Al3+4) size of cation increases and size of the anion is constant. then lattice energy decreases,,,,,,,,,,,,,,,,
