d-Block Configuration and Metallic Trends

The source begins d-block with the general electronic configuration and metallic properties of transition elements.

(n-1)d^{1-10}ns^{0-2}

Property	Source-backed point
Metallic character	Nearly all display high tensile strength, ductility, malleability, conductivity and metallic lustre.
Metallic structures	With exceptions of Zn, Cd, Hg and Mn, they have one or more typical metallic structures at normal temperatures.
Hardness/volatility	Except Zn, Cd and Hg, transition elements are very hard and have low volatility.
Melting/boiling	Melting and boiling points are generally very high.
