Why `Ag` is a noble metal and `K` is a highly reactive metal ?

Text Solution

AI Generated Solution

To understand why silver (Ag) is classified as a noble metal while potassium (K) is a highly reactive metal, we need to analyze their electronic configurations and the concepts of ionization enthalpy and electropositivity. ### Step-by-Step Solution: 1. **Define Noble Metals and Reactive Metals**: - Noble metals are metals that are resistant to corrosion and oxidation in moist air. They do not easily lose electrons and thus do not readily participate in chemical reactions. - Highly reactive metals are those that easily lose electrons to form positive ions, making them more likely to participate in chemical reactions. ...
