Question

Is ionic bond formation exothermic or endothermic?

Answer 1

Explanation:

Exothermic: An exothermic reaction is a type of reaction in which heat is released as a result of the reaction.

Endothermic: The system absorbs heat from the surroundings, lowering the ambient temperature.

1. The energy of bonded atoms is lower than that of un-bonded atoms that are isolated.
2. Because bonded atoms have a lower energy state than isolated atoms, bonds exist.
3. As a result, heat should be released to reduce energy consumption or increase stability.
4. Exothermic reactions are those in which the formation of bonds increases stability.

Hence, ionic bond formation is exothermic.
