Question

The interaction abundantly found in $Cu,Ag$ and $Au$ is:

• A. attraction
• B. repulsion
• C. ion-ion
• D. electron-electron

Answer 1

The correct option is C ion-ion

The interaction abundantly found in $Cu,Ag$ and $Au$ is ion ion interaction. These are metals. They lose valence electron to form positively charged ions. Hence, the interaction present is ion ion interaction.
