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.

Is an ionic compound exothermic?
The formation of an ionic compound is usually exothermic because energy is released when the positive and negative ions come together to form a stable compound with strong electrostatic forces of attraction.
Why is formation of ionic compounds exothermic?
It is exothermic because heat is released. ATP is on the products side. =] =) =I =p
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.
What is an endothermic compound and what is an exothermic compound?
An endothermic compound absorbs heat or energy from its surroundings during a chemical reaction, causing a decrease in temperature. An exothermic compound releases heat or energy into its surroundings during a chemical reaction, causing an increase in temperature.
What is the relationship between the formation reactions that are exothermic and their corresponding enthalpy of formation values (hf)?
The relationship between exothermic formation reactions and their enthalpy of formation values is that exothermic reactions release heat energy when the compound is formed. This results in a negative enthalpy of formation value (hf) because the reaction is giving off energy.
Is the formula of a compound ionic?
A compound is considered ionic if it is composed of a metal and a nonmetal. Ionic compounds form when electrons are transferred from the metal to the nonmetal, resulting in the formation of ions held together by electrostatic forces. The formula of an ionic compound represents the ratio of the ions present in the compound.
Describe the energy change associated with ionic bond formation and relate it to stability?
The energy change associated with ionic bond formation is typically exothermic, meaning energy is released. This is because when an electron is transferred from one atom to another to form an ionic bond, the resulting ions are in a lower energy state than the separate atoms. The release of energy contributes to the stability of the ionic compound formed.
Is magnesium chloride an ionic or covalent bond?
Magnesium chloride is a compound, not a bond of any kind. The compound is ionic.
Is LaP an ionic or molecular compound?
LaP (lanthanum phosphide) is an ionic compound. Lanthanum is a metal while phosphorus is a non-metal, leading to the transfer of electrons from lanthanum to phosphorus and the formation of ionic bonds between the two elements.
Does sodium ascorbate have an ionic or covalent bond?
Sodium ascorbate has an ionic bond. Sodium donates an electron to ascorbate, resulting in the formation of an ionic compound.
Is strontium chloride ionic or covalent bond?
Strontium chloride is an ionic compound. Strontium, being a metal, donates its electrons to chlorine, a nonmetal, resulting in the formation of ionic bonds between the two elements.
Is Nickel II acetate an ionic compound?
Nickel II acetate is considered an ionic compound. It is formed from the cation of nickel(II) and the anion of acetate, and the electrostatic attraction between these oppositely charged ions results in the formation of an ionic compound.
