D-Block Elements in the Periodic Table

Definition

• A D-block element is a chemical element in the d-block of the periodic table
• The d-block is the section of the periodic table that includes groups 3-12
• D-block elements are also known as transition metals

Characteristics

• D-block elements exhibit multiple oxidation states
• They often exhibit catalytic properties
• They form colored ions and compounds
• They are good conductors of electricity
• They are often magnetic

Electronic Configuration

• D-block elements have a partially filled d subshell in their atomic orbitals
• The d subshell is being filled in these elements
• The electronic configuration of D-block elements is (n-1)d^1-10 ns^1-2

Categories of D-block Elements

• Inner Transition Metals: These are elements in the f-block of the periodic table, but are often included with the D-block elements
  • Lanthanides (La - Lu) and Actinides (Ac - Lr)
• Outer Transition Metals: These are the typical D-block elements
  • Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn

Occurrence

• D-block elements are found in the Earth's crust, often in ores or minerals
• They can be extracted through various methods, including electrolysis and reduction
• They are used in a wide range of applications, including catalysis, electronics, and construction materials
