INTRODUCTION

What is Transition Metal?

• Definition of a Transition Element: • All transition elements are metals with the following
Any element in any of the series of elements with properties:
atomic numbers 21–29, 39–47, 57–79, and 89–107,
that in a given inner orbital has less than a full quota Solids with shiny surfaces
of electrons.
Very hard compared to metals in Groups 1
and 2

Have high densities

Have high melting points and boiling
points

Uses of Transition Metal

Iron

• Appearance :
A shiny, greyish metal that rusts in damp air.

• Uses :
Iron is very useful, especially when mixed with other
elements to prepare alloys such as steel.
Such alloys have many industrial uses such as the
manufacture of construction and building materials,
tools, vehicles, cosmetics, paints, fertilizers, etc.,
making it extremely important for the world economy.
Cast iron is usually used to make covers for manholes.
Iron is also used as a catalyst, while artificially
extracting ammonia in the Haber process.
Most importantly, iron is a very important element in
the bodies of many animals, used to create
hemoglobin which is used to carry oxygen in the
blood.

Uses of Transition Metal

Manganese

• Appearance :
A hard, brittle, silvery metal.

• Uses :
Manganese is too brittle to be of much use as a pure
metal. It is mainly used in alloys, such as steel.
Most of the manganese is found on the floors of the
oceans around the world.
Majority of the manganese that is extracted goes into
the production of ferro-manganese steel. The
remainder goes into creating components of electronic
devices, owing to its low temperature coefficient of
resistivity
It is also used to create potassium permanganate,
which is used in chemical labs across the world.
Manganese is also used in dry batteries, the
manufacture of bricks and glass, fertilizers, and the
production of magnets that are used in televisions.

Uses of Transition Metal

Cobalt

• Appearance :
A lustrous, silvery-blue metal. It is magnetic.

• Uses :
This element is quite rare, and is primarily used in the
ceramics and paint industry to create blue colors.
Some compounds of cobalt are used in the creation of
aldehydes that are useful in the chemical industry. It
is also used to make stellite, an alloy used for making
drill bits.
This element is also used to produce high
temperature-resistant alloys that are used in the
manufacture of gas turbines.
Magnetic alloys such as alnico steel are also
manufactured with the help of cobalt.

Uses of Transition Metal

Zinc

• Appearance :
A silvery-white metal with a blue tinge. It tarnishes in
air.

• Uses :
Over 6 million tons of zinc is produced annually,
majority of which is used to coat various metals to
prevent corrosion and rust.
It is also used in the manufacture of batteries and in
the process of die casting.
It is also an important component of brass alloys.
Zinc oxide is used in manufacturing textiles, paints,
and rubber products.
Zinc sulfide is used in televisions, clocks, and
fluorescent light bulbs. The element is also a part of
rat poisons.
The human body uses zinc to heal wounds and to
store insulin inside the pancreas.

CONCLUSION

I have learnt that the transition elements are actually used in our daily life without us realising the element.
Transition metal is an any of various chemical elements that have valence electrons—i.e., electrons that can
participate in the formation of chemical bonds—in two shells instead of only one. While the term transition has
no particular chemical signi cance, it is a convenient name by which to distinguish the similarity of the atomic
structures and resulting properties of the elements so designated. They occupy the middle portions of the long
periods of the periodic table of elements between the groups on the le -hand side and the groups on the right.
Speci cally, they form Groups 3 (IIIb) through 12 (IIb).

A P P R E C I AT I O N

First, I would like to show my greatest appreciation to my Chemistry teacher —— Pn. Yuu Yee Mee, for
guiding us throughout the project and eager to give us some advice in order to improve the quality of our project
and achieve the quali ed standard.

Second, I want to thank my dear friends for their help during the preparation of this report. In addition, they
will give me some suggestions to improve my report. I would like to express my sincere gratitude to you and thank
you for your help.
