Interpretation Introduction

Interpretation:

The reason why sodium chloride has higher melting point than water has to be given.

Concept Introduction:

Ionic Bonding:

Ionic bonding is the complete transfer of valence electrons between atoms.  In ionic bonds the metal loses electrons to become a positively charged cation whereas the nonmetal accepts those electrons to become a negatively charged anion.

Covalent bonding:

Covalent bonding is the sharing of electrons between atoms.  This type of bonding is occurs between two atoms of the same element.
