Which of the following statements are correct about Zn, Cd and Hg?<br>(I) they exhibit high enthalpi — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Transition metals typically possess partly filled d-orbitals, which allows them to exhibit several key characteristics. Step 2: These characteristic properties include the ability to show variable oxidation states (due to small energy gaps between (n-1)d and ns orbitals), a strong tendency to form coordination complexes (due to small, highly charged cations and vacant orbitals), and the formation of colored compounds (due to d-d electronic transitions). Step 3: Since all of the listed properties (a, b, and c) are standard characteristics of transition metals, the correct choice is 'none of these', corresponding to option (d).
