D-block elements in the periodic table, including 3d, 4d, 5d, and 6d series.

Arrangement of electrons in an atom's orbitals, noted as (n-1)d1-10 ns1-2 for transition metals.

Valencies that transition metals can exhibit, due to loss of electrons from (n-1)d and ns orbitals.

Transition metals can form complex compounds with ligands, affecting their geometry.

Half-filled and fully-filled d-orbitals are more stable than others, influencing electron configurations like in Cr and Cu.

Their configurations are represented by (n-1)d10ns2, indicating full orbitals and no transition properties.

Scandium has an incompletely filled 3d orbital (3d1), making it a transition element.

Includes variable oxidation states, colored ions, complex formation, catalytic properties, and paramagnetism.

Transition elements can exist in multiple oxidation states due to their electron configuration.
