Transition Metals and Their Applications

Transition Metals Overview  

Between Group 2 and Group 3 of the periodic table lie the transition metal elements that form the backbone of industrial chemistry. Roughly 80% of the periodic table consists of metals, highlighting their dominance in both natural and synthetic processes.  

Metallic Nature  

Metals are generally basic, while non‑metals are acidic, reflecting their contrasting chemical behaviours.  

Properties of Transition Metals  

Transition metals exhibit unique characteristics that distinguish them from other groups:  

- High melting and boiling points compared to Group 1 metals.  

- Variable valency, except for a few exceptions such as Sn³⁺, Zn²⁺, and Ag⁺.  

- Colored compounds, though their salts are typically white.  

- Excellent conductors of heat and electricity, and often act as catalysts in chemical reactions.  

Industrial Applications  

Transition metals play a vital role in large‑scale manufacturing processes:  

- Iron (Fe): Used in the Haber’s Process for the manufacture of ammonia (NH₃).  

- Vanadium(V) oxide (V₂O₅): Catalyst in the Contact Process for producing sulfuric acid (H₂SO₄).  

These metals bridge the gap between chemistry and industry, combining strength, versatility, and reactivity to drive innovation.
