Lattice energy

When an atom donates electron it forms positive ion. When any atom gains electron it forms negative ion. In order to form a new compound these oppositely charged ion must have to combine together. When positively charged ion and negatively charged ion combine together and forms new compound some energy releases. The released energy to form one mole of compound by combining the anion and cation is termed as lattice energy. Lattice energy determines the nature of the bond. How strength the bond will be that depends on lattice energy. Greater the lattice energy greater the ionic bonds strength. The strength of the ionic bond and lattice energy relationship can express graphically. If we plot lattice energy vs strength of the ionic bond, there found that increasing of ionic bond with increasing of lattice energy. Some factors can influence on lattice energy. These factors are size of the ion and charges on ion.
