Nacl have greatr lattic energy as campard to kcl bcz cl have same but size of Na is small and size of k is grtr.

Lattice energy refers to the amount of energy released or absorbed when ions in the gas phase combine to form a solid ionic compound. It is a measure of the strength of the ionic bonds in the compound. A higher lattice energy implies stronger ionic bonding.

To determine which compound, KCl (potassium chloride) or NaCl (sodium chloride), has a higher lattice energy, we need to consider the charges and sizes of the ions involved.

First, let's compare the charges of the ions. Both KCl and NaCl consist of one positively charged ion (K⁺ or Na⁺) and one negatively charged ion (Cl⁻).

Now, let's consider the sizes of the ions. Generally, smaller ions have stronger ionic bonds because the oppositely charged ions are closer to each other and experience stronger electrostatic attraction. Potassium (K⁺) has a larger atomic radius than sodium (Na⁺), meaning that the chloride ion (Cl⁻) is farther away from the potassium ion compared to the sodium ion.

In other words, K⁺ and Cl⁻ ions have a larger distance between them compared to Na⁺ and Cl⁻ ions. As a result, the electrostatic attraction is weaker in KCl compared to NaCl.

Therefore, NaCl has a higher lattice energy compared to KCl because the smaller size of sodium ions allows for stronger electrostatic attraction with chloride ions.

To summarize, NaCl has a higher lattice energy because sodium ions (Na⁺) are smaller than potassium ions (K⁺), resulting in stronger electrostatic attraction with chloride ions (Cl⁻).
