Look at the problem from the other angle why does it take energy to break up an ionic lattice. It is because of the electrostatic attrction of the ions which has to be overcome. A measure of the is energy is the lattice enthalpy which depends on the charges, th einterionic distances and the geometry of the lattice.

Generally speaking, "bond breaking" is endothermic and "bond making" is exothermic. When an ionic bond happens, that's usually a bond between two monatomic ions, and it's being formed. Since no bond is breaking, you have an overall exothermic process.

Why is formation of ionic compounds exothermic?

It is exothermic because heat is released. ATP is on the products side. =] =) =I =p


What is an endothermic compound and what is an exothermic compound?

Compounds are not generally considered endothermic or exothermic. These terms refer to processes. So, the process of formation, or the process of decomposition, would be an endothermic process or an exothermic process.


Is an ionic compound exothermic?

A compound is never exothermic. Its reaction with some other substance is endothermic or exothermic like when calcium oxide reacts with water large amount of heat is evolved.


Which of the following favors formation of an ionic compound?

c)


Is the formation of a stable ionic compound exothermic?

For an element to lose an electron, that electron must become excited to the point it can escape the attractive force. This requires a net energy input, making it endothermic.


A great deal of energy is produced when an ionic compound is formed?

False. Formation of a compound is usually exothermic because a Noble Gas configuration forms around each atom. Therefore energy is given off during formation, and the atoms in the compound are more stable.


Are ions in a ionic compound in a lattice formation?

At least, one anion and one cation participate in forming a crystalline ionic lattice. Every ionic compound forms a lattice, they do not form molecules.

What is the definition of enthalphy?

The lattice energy of an ionic solid is a measure of the strength of bonds in that ionic compound. It is usually defined as the enthalpy of formation of the ionic compound from gaseous ions and as such is invariably exothermic. The concept of lattice energy has initially been developed for rocksalt-structured and sphalerite-structured compounds like NaCl and ZnS, where the ions occupy high-symmetry crystal lattice sites. In case of NaCl, the lattice energy is the energy released by the reaction


One of the first steps in the formation of an aqueous solution of an ionic compound is disruption of the ionic bonds holding the compound together in a crystal lattice?

This step alone cannot be used to predict solubility.
