Determine the order of the given sodium halides based on their properties.

Identify the sodium halides.

The given sodium halides are NaF, NaI, NaCl, and NaBr.

Consider the trend in the periodic table.

In the periodic table, halogens (F, Cl, Br, I) are in Group 17. As you move down the group, the atomic size increases.

Analyze the properties affected by the atomic size.

As the atomic size increases, the bond length between sodium and the halogen increases, which affects properties such as melting point, boiling point, and solubility.

Arrange the sodium halides in order of increasing atomic size of the halogen.

The order of increasing atomic size of the halogen is: F < Cl < Br < I.

\(\boxed{\text{NaF, NaCl, NaBr, NaI}}\)

\(\boxed{\text{NaF, NaCl, NaBr, NaI}}\)
