No, MgO has a higher lattice energy than NaCl. This is because Mg2+ and O2- ions have a greater charge than Na+ and Cl- ions, leading to stronger electrostatic forces of attraction in MgO.

Why lattice energy of nacl is greater then kcl and kbr?
The lattice energy of NaCl is greater than that of KCl and KBr because NaCl has higher charge densities on its ions due to smaller atomic sizes, resulting in stronger electrostatic interactions between ions. In contrast, KCl and KBr have larger ionic sizes which lead to lower charge densities and weaker electrostatic attractions, resulting in lower lattice energies.
Can lattice space of NaCl crystal be determined by diffraction experiment with sodium yellow light?
No, the lattice spacing of a NaCl crystal cannot be determined with sodium yellow light alone because the wavelength of light used for diffraction needs to match the spacing between planes in the crystal lattice. Since the lattice spacing of NaCl is much smaller than the wavelength of sodium yellow light, other types of radiation such as X-rays are typically used for diffraction experiments to accurately determine the lattice spacing.
Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
The lattice energy of potassium bromide is more exothermic than that of rubidium iodide because potassium and bromine have smaller atomic sizes and higher charges, which leads to stronger ionic bonding in potassium bromide. Rubidium and iodine have larger atomic sizes and lower charges, resulting in weaker ionic bonding in rubidium iodide. The stronger ionic bonding in potassium bromide requires more energy to break, resulting in a more exothermic lattice energy.
Why is the boiling point of NaCl higher than sucrose?
The boiling point of NaCl is higher than sucrose because NaCl forms stronger ionic bonds between sodium and chloride ions, which require more energy to break compared to the weaker intermolecular forces that hold sucrose molecules together. This results in a higher boiling point for NaCl compared to sucrose.
Does calcium oxide have a higher lattice energy than magnesium oxide?
Yes, calcium oxide has a higher lattice energy than magnesium oxide. This is due to the higher charge of the calcium ion compared to the magnesium ion, leading to stronger electrostatic attraction between the ions in the lattice structure.

The lattice energy of NaCl is greater than that of KCl and KBr because NaCl has higher charge densities on its ions due to smaller atomic sizes, resulting in stronger electrostatic interactions between ions. In contrast, KCl and KBr have larger ionic sizes which lead to lower charge densities and weaker electrostatic attractions, resulting in lower lattice energies.
When is lattice energy greater than hydration energy?
Lattice energy is greater than hydration energy when the overall energy released during the formation of the crystal lattice (lattice energy) is higher than the energy absorbed during the separation of ions from the lattice by water molecules (hydration energy). This typically occurs for highly charged ions that form strong ionic bonds and have a high charge-to-size ratio.
Why does NaCl have a high melting point than KCl?
This can be rationalised by looking at the lattice energy. Using Madelungs method the smaller Na+ ion causes a stronger coulombic attraction making it harder to beak up the lattice and increasing the mp.
Can lattice space of NaCl crystal be determined by diffraction experiment with sodium yellow light?
No, the lattice spacing of a NaCl crystal cannot be determined with sodium yellow light alone because the wavelength of light used for diffraction needs to match the spacing between planes in the crystal lattice.

Why do sugar dissolve faster then salt in water?
For dissolving any solute the solvation energy of the solvent has to be more than the lattige energy of the solute. In this case the lattice energy of Nacl[salt] is more than that of sugar. Hence it takes more time to dissolve in water. ---- Akashraj Ghosh.
Is iron carbonate a soluble salt?
No, iron carbonate is not a soluble salt. It is a sparingly soluble salt, meaning it only partially dissolves in water.
Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
The lattice energy of potassium bromide is more exothermic than that of rubidium iodide because potassium and bromine have smaller atomic sizes and higher charges, which leads to stronger ionic bonding in potassium bromide. Rubidium and iodine have larger atomic sizes and lower charges, resulting in weaker ionic bonding in rubidium iodide. The stronger ionic bonding in potassium bromide requires more energy to break, resulting in a more exothermic lattice energy.
Why is lattice energy of MgF2 greater than MgCl2?
The lattice energy of MgF2 is greater than MgCl2 because fluorine ions are smaller than chloride ions, leading to stronger electrostatic attraction between the ions in MgF2. Additionally, fluorine has a higher charge density compared to chlorine, resulting in stronger ionic bonding in MgF2.
Why is the boiling point of NaCl higher than sucrose?
The boiling point of NaCl is higher than sucrose because NaCl forms stronger ionic bonds between sodium and chloride ions, which require more energy to break compared to the weaker intermolecular forces that hold sucrose molecules together. This results in a higher boiling point for NaCl compared to sucrose.
Does calcium oxide have a higher lattice energy than magnesium oxide?
Yes, calcium oxide has a higher lattice energy than magnesium oxide. This is due to the higher charge of the calcium ion compared to the magnesium ion, leading to stronger electrostatic attraction between the ions in the lattice structure.
What can you say about the relative magnitudes of the lattice energy of lithium iodide and its heat of hydration?
The lattice energy of lithium iodide is typically larger than its heat of hydration. This means that more energy is required to break the ionic bonds in the solid lattice of lithium iodide than is released when the ions are hydrated in solution.
Which has higher lattice energy AgCl and AgBr?
AgCl has a higher lattice energy than AgBr because Cl- is a smaller ion than Br-, resulting in stronger electrostatic interactions in AgCl.
