Compare NaCl and CsCl with respect to ease of formation and also strength of ionic bond. |
| Answer» Solution :Ionic compounds are formed easily between larger cation and smaller anion. This is because an atom whose atomic radius is large can FORM a cation easily and an atom that has a small atomic radius can form an anion easily. `Cs^(+)` ION can be formed more easily than `Na^(+)` ion. FORMATION of CsCl is easier than the formation of NACL. Between NaCl and CsCl, as the anion is the same, that is, `Cl^(-)`, the sizes of the cations are compared. `Cs^(+)` has a larger ionic radius than `Na^(+)`. THUS, the strength of ionic bond is more in NaCl than CsCl. | |
