Topics covered in d- and f-Block Elements for JEE Mains Chemistry.
Topics in d- and f-Block Elements
1
Introduction and Electronic Configuration
- d-block elements: General electronic configuration (n-1)d¹⁻¹⁰ ns¹⁻²
- Transition elements have incompletely filled d-orbitals in ground state or stable oxidation states
- Zn, Cd, Hg are non-typical transition elements (completely filled d-orbitals)
2
Physical Properties
- Metallic character: High tensile strength, thermal/electrical conductivity, metallic luster
- High melting and boiling points due to strong metallic bonding involving d-electrons
- Atomic radii trend: Generally decrease across period, then remain constant, slight increase at end
3
Variable Oxidation States
- Multiple oxidation states due to small energy difference between (n-1)d and ns orbitals
- Common oxidation states differ by unity (+2, +3, +4, +5, etc.)
- Maximum oxidation state = Group number (up to Mn), then decreases
4
Ionization Energies and Electrode Potentials
- Ionization energies generally increase across series with some irregularities
- IE₁ values lie between s-block (lower) and p-block (higher) elements
- High IE₂ for Cr and Cu due to stable d⁵ and d¹⁰ configurations respectively
