Here’s a explanation of transition metals:
Definition
Transition metals are the elements found in the middle of the periodic table (Groups 3–12).
They are metals with partially filled d-orbitals in their atoms or ions.
Properties of Transition Metals
- Good conductors of heat and electricity
- Shiny (lustrous) and hard
- High melting and boiling points
- Can form different oxidation states (like Fe²⁺ and Fe³⁺)
- Often form colored compounds
- Act as catalysts in chemical reactions
- Can form complex ions with ligands
Examples
- Iron (Fe)
- Copper (Cu)
- Nickel (Ni)
- Chromium (Cr)
- Manganese (Mn)
Uses
- Iron (Fe): construction (steel)
- Copper (Cu): electrical wires
- Platinum (Pt): jewelry, catalysts
- Titanium (Ti): aircraft, implants
In short: Transition metals are the middle block elements (Groups 3–12) that have special metallic properties, form colored compounds, and are very useful in industry.
