Because the atomic weight of sodium is greater than the atomic weight of lithium; sodium is under lithium in the column of alkali metals.
Sodium fluoride has a higher boiling point than lithium fluoride due to stronger intermolecular forces of attraction between sodium and fluoride ions in sodium fluoride compared to lithium and fluoride ions in lithium fluoride. This stronger bond requires more energy to break, leading to a higher boiling point for sodium fluoride.
The higher melting point of sodium fluoride compared to sodium iodide is due to stronger forces of attraction between the ions in the crystal lattice of the fluoride compound. Fluoride ions are smaller and have a higher charge density compared to iodide ions, leading to stronger electrostatic forces between the ions in sodium fluoride, resulting in a higher melting point.
Lithium fluoride (LiF) is a chemical salt , equivlanet to sodium chloride (NaCl).
Lithium fluoride (LiF) forms as a colorless solid with a high melting point. It is composed of lithium cations (Li+) and fluoride anions (F-) arranged in a 3D lattice structure. LiF is highly soluble in water and is commonly used in various applications, including in the production of ceramics and glass.
Sodium fluoride is the only compound in sodium fluoride.

Lithium fluoride (LiF) is a chemical salt , equivlanet to sodium chloride (NaCl).
The intermolecular forces holding F2 molecules together are relatively weak in comparison to the forces binding NaF molecules.
Examples: sodium chloride, lithium fluoride, calcium carbonate.
Lithium fluoride and hydrogen fluoride, also known as hydrofluoric acid.
Lithium and fluorine combine to form lithium fluoride. Another element that could combine with fluorine in a similar manner to lithium is sodium, which would form sodium fluoride. Both lithium and sodium belong to the alkali metal group and share similar chemical properties.
Examples: clacium chloride, sodium bromide, lithium fluoride.
Sodium iodide has the highest molar mass among the compounds listed, with a molar mass of 149.89 g/mol. Sodium bromide has a molar mass of 102.89 g/mol, sodium chloride has a molar mass of 58.44 g/mol, lithium bromide has a molar mass of 86.85 g/mol, and lithium fluoride has a molar mass of 25.94 g/mol.

Lithium is softer than sodium. Sodium is harder because it has a higher atomic number and more electrons, which results in stronger metallic bonding compared to lithium.
