AI Generated Solution

To solve the question regarding the stability of alkali metals and coinage metals, as well as the comparison of their cation polarizing power, we can break it down into two parts. ### Part (a): Stability of Alkali Metals vs. Coinage Metals 1. **Identify the Groups**: - Alkali metals: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs). - Coinage metals: Copper (Cu), Silver (Ag), Gold (Au). ...

in an ionic bond the cation tends to polarise the electron cloud of the anion by pulling electron density towards itself This causes development of covalent character in the ionic bond because the electron density gets localised in between the nuclei The tendency of the cation to bring about the polarisation of the anion is expressed as its polasising power The ability of ion to undergo polarisation is called its polarisability The polarising power of a cation or an anion is decided on the basis of F ajans' rules as follows .
