Question: What Is the Difference Between an Ionic and Covalent Bond?

Answer: The difference between an Ionic and Covalent Bond as under:
In an ionic bond, the atoms are bound together by the attraction between oppositely-charged ions. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt. 
In a covalent bond, the atoms are bound by shared electrons.Usually, an electron is more attracted to one atom than to another, forming a covalent bond. For example, the atoms in water, H2O, are held together by covalent bonds.
