Question

Which has high melting point - NaF or NH3

Answer 1

NaF has comparatively high melting point because it is an ionic bond and the forces of attraction between the ions are great.

Answer 2

The reason why NaF would have thehighest melting point is because , if you look at the electronegativity values fluorine has the highest hence it have the greatest pull or attraction towards the electrons in the ionic bond , resulting in a really strong sodium positive ion and a strong negative fluorine ion ,this ...
