Question

Why do transition elements have high enthalpy of hydration?

Answer 1

Transition elements:

1. Elements that have partially filled d orbitals are termed transition elements.
2. Transition elements are found in groups 3 to 12 in the periodic table.

Transition elements have a high enthalpy of hydration as:

1. The Transition elements have high enthalpy of hydration
2. The presence of strong metallic bonds is the major reason for the transition elements having a high enthalpy of hydration.
3. It further leads to the unpaired electrons in the (n – 1) d subshell.
4. The atoms of the transition elements are tightly packed.
5. The charge density is more for smaller ions which lead to higher values of hydration of enthalpy in transition elements.
6. Transition metal element ions are mostly small in size with a high charge.
