Question

Distinguish the endothermic and exothermic energy changes associated with ionic bond formation, and relate it to stability​

Answer 1

Answer:

When ionic compounds are formed, energy is released which is exothermic energy. If the energy released during bond formation is reabsorbed, the ionic bond holding the positive ions and negative ions together will break apart which is endothermic energy.

Explanation:

Answer 2

The formation of an ionic crystal lattice from its constituent ions is an exothermic process.

Endothermic changes are energy changes in which energy is absorbed while exothermic energy changes are those energy changes in which energy is evolved.

During the formation of an ionic bond, the metal looses electron(s). This is an endothermic process. The nonmetal accepts electrons. This is an exothermic process.

When the ionic crystal is formed, energy is given out because the energy of the lattice is less than the energy of the isolated ions. This heat change is exothermic.
