Why does NaCl have a higher melting point than Nai?

C. The sodium chloride has a higher melting point because of the greater charges of the ions, and hence the greater force of attractions between them. The sodium chloride has a higher melting point because its ions are smaller, which allows oppositely charged ions to get closer.

How does sodium chloride have a high melting point?

1,474°F (801°C)
Sodium chloride/Melting point

Why melting point of sodium fluoride is higher than that of sodium iodide?

Answer: Fluoride ions are smaller than chloride ions, which in turn are smaller than bromide and iodide ions. Stronger attractions between the ions in the crystal lattice means a higher temperature is required to melt the crystal.

Why does NaCl have a higher boiling point than NaF?

(B) NaCl will have a boiling point between that of Naf and MgO because the covalent character of the bonds in NaCl is intermediate between that of MgO and NaF.

Why the melting point of sodium iodide is lower than the melting point of sodium bromide?

This is because when you go down the halogen group, you add another shell of electrons and increase the amount of electron shielding. So the valence electrons feel less of a pull from the nucleus, and are not tightly bound.

Why is the melting point of sodium iodide lower than the melting point of sodium bromide?

Why is the melting point of sodium iodide is lower than the melting point of sodium bromide?

Why does NaCl have a lower boiling point than NaF?

A NaCl will have a lower boiling point than Naf because the coulomhic attractions are weaker in NaCl ihan in NaF. (B) NaCl will have a boiling point between that of Naf and MgO because the covalent character of the bonds in NaCl is intermediate between that of MgO and NaF.

Why does sodium iodide have a lower melting point than sodium chloride?
