Q1. A metallurgist compares the hardness of different metals. Which element exhibits the strongest metallic bonding due to the involvement of (n-1)d electrons?
Answer: Iron
Explanation: Transition metals have strong metallic bonds involving d-electrons; Group IA metals are tempting but have weaker bonds with only one s-electron.
