Question

What is higher lattice energy of ionic compound? ​

Answer 1

Explanation:

Which has higher lattice energy: MgO or LiF ? A compound has higher lattice energy if it's ions have smaller size and greater charge. Li cation is smaller than Mg cation => +1 for (LiF) Fluoride anion is smaller than oxide anion => +1 for (LiF) Mg cation has greater charge than Li cation => +1 for (MgO)

Answer 2

Answer: Lattice energy is a type of potential energy that relates to the ability of ionic solids. It is generally higher for ionic compounds due to their hard and rigid structure.

Explanation:

Ionic compounds are very stable,which means it takes a lot of energy to break their bonds. The type of energy we are discussing is called lattice energy or lattice enthalpy because it refers to ionic solids where ions are arranged in what is known as crystal lattice.

Factors like strength of ionic bond and ionic radius affect the lattice energy.
