Question

no liquid ionic compound are known but many of the known covelant compound are liquid and some are gases Account for these difference
​

Answer 1

Answer:

Ionic compounds are compounds that are composed of oppositely charged ions, anions and cations. The force which holds the two ions (charged atoms) together is called the electrostatic force, and the bond that exists between them is called an ionic bond. In an ionic compound, there are millions of ions present and all these ions are held together by electrostatic forces. These forces are very strong, holding ions firmly in place and thus forming a crystal lattice structure. At normal room temperature, the strength of an ionic bond is much greater than the individual kinetic energy of the two ions participating in the bond. Hence, ionic compounds exist only as solid under normal conditions.
