🔥D-BLOCK INORGANIC CHEMISTRY : 02🔥 | SURE SHOT SESSION | HSP SIR |

D-block elements (Groups 3-12) are transition metals characterized by filling inner -orbitals, featuring high melting points, variable oxidation states, and complex formation. Located between and -blocks, they are vital for industrial catalysis (e.g., Pt, Pd) and materials science, exhibiting paramagnetism and colorful compounds. Key Aspects of D-Block Inorganic Chemistry Electronic Configuration: Generally . Notable exceptions exist where -orbitals are filled to increase stability, such as Chromium ( ) and Copper ( ). Transition Elements Definition: Not all -block elements are true transition metals. A transition metal must have a partially filled -orbital in its ground state or a stable ion. Not Transition Metals: Group 12 (Zn, Cd, Hg) have completely filled configurations in their ground and common oxidation states. Physical Properties: High density, high metallic bonding strength, and high melting/boiling points. Key Chemical Properties: Variable Oxidation States: Due to the small energy gap between and orbitals. Complex Formation: Tendency to form coordination compounds (e.g., ). Colored Compounds: Electrons transition between -orbitals ( - transitions) when ligands are present. Catalytic Activity: Used in industry for hydrogenation, oxidation, and polymerization (e.g., Ni, V, Pt). Series: Includes the 3d (Sc-Zn), 4d (Y-Cd), 5d (La-Hg), and 6d series
