Objective

1. Determine the position of transition elements in the Periodic Table of Elements.
2. Explain the special characteristics of a few transition elements with examples.
3. List the uses of transition elements in industry.

Position

• Transition elements are placed in Group 3 and 12 in the Periodic Table of
Elements. Examples of transition elements include chromium, Cr, manganese, Mn,
iron, Fe and copper, Cu. The pink portion in the below figure shows the position
of transition elements in the Periodic Table of Elements.

Iron (Fe)

Characteristic
• ductile, gray, relatively soft metal
• moderately good conductor of heat and electricity
• attracted by magnets
• readily magnetized
• very reactive and rusts readily in moist air (pure metal)

Platinum

Characteristic
• precious metal
• soft, silvery-white
• dense with a beautiful lustrous sheen
• one of the of the six platinum group metals

Titanium

Characteristic
• light, silvery-white, hard, lustrous metal
• excellent strength and corrosion resistance
• high strength to weight ratio
• corrosion rate is low

Uses of Transition Elements in Industry

• Used as a catalyst in industry
• Example :

Iron is used to manufacture steel and other alloys important in construction and manufacturing.

Platinum is used in jewelry, decoration and dental work. The metal and its alloys are also used for electrical
contacts, fine resistance wires and medical / laboratory instruments.

Titanium metal is used as an alloying agent with metals including
aluminum, iron, molybdenum and manganese. Alloys of titanium are mainly used in aerospace, aircraft
and engines where strong, lightweight, temperature-resistant materials are needed.
