## Does CaO have a high lattice energy?

Thus, **Lattice Energy of CaO is greater than MgBr2. Lattice dissociation enthalpy is a measure of the forces of attractions between the positive and negative ions.**

## What is the lattice energy of calcium?

2195.2 kJ/mol

## How do you calculate the lattice enthalpy of calcium oxide?

In both CaO and MgO, the charges are +2 and -2, so the choice is between these two oxides. The smallest ions will be able to get closest to each other. Mg2+ is smaller than Ca2+ , so **MgO has the largest lattice energy**

## Does NaCl or CaO have higher lattice energy?

If we look at the ions we can clearly see that CaO have ions that are doubly charged. This means that CaO would have **higher lattice energy. ANSWER: Compounds with doubly charged ions like CaO will most likely have higher lattice energy than compounds with singly charged ions like NaCl.**

## Which has higher lattice energy KCl or CaO?

Thus as **calcium oxide CaO has greater charge of (+2), it has greater lattice energy as compared to KCl which has the charge (+1). Hope it helps.**

## Does CaO or MgO have a higher lattice energy?

In both CaO and MgO, the charges are +2 and -2, so the choice is between these two oxides. The smallest ions will be able to get closest to each other. They will have the smallest distance between centres and will have the largest lattice energies. Mg2+ is smaller than Ca2+ , so **MgO has the largest lattice energy**

## Which has more lattice energy CaF2 or CaO?
