2. WHAT IS CARBON ?
• Carbon is a non-metal
• Carbon is the sixth element in the
periodic table which is located
between boron (B) and nitrogen (N)
• Elemental symbol for it is the letter C
• It is the basic building block for all
forms of life on Earth
• Fortunately, carbon is also one of the
most abundant element on our planet
• Fourth most abundant element in the
universe
• Second most abundant element in
the human body

3. FORMS AND STATES OF CARBON
• Scientists describe carbon into three
different forms known as allotropes;
• Carbon is solid at room temperature just
like the non-metal sulfur
• Melting point of Carbon is 3367°C
• Boiling point of Carbon is 4827°C
Allotropes* : Each of two or more different physical forms in which an element can exist
MELTED CARBON
Recently, these melted carbon was
found under western USA

4. DIAMOND PROPERTIES & INFORMATION
• Diamonds are one of the allotropes of
carbon
• One of the most famous and popular
gemstones in the market today
• It is world's hardest natural material and
has been assigned a hardness of 10 on
the Mohs hardness scale
• Diamond is a good conductor of heat but
bad conductor of electricity
• Diamond reserves are found in Canada,
Brazil, Russia, China, Australia, Angola,
Guinea, Sierra Leone, D.R. Congo,
Tanzania, Namibia, Zimbabwe,
Botswana and South Africa

5. GRAPHITE PROPERTIES & INFORMATION
• Graphite is a crystalline* form of the
element carbon with its atoms arranged in
a hexagonal structure
• A good conductor of heat and electricity
• At high temperature it turns into diamond
• The "lead" filling in pencils is in fact composed of
a mixture of Graphite and clay
• Graphite's main function is as a lubricant
• Largest producer is China producing about 66%
of the graphite which is followed by India
Crystalline* : having the structure and form of a crystal

6. FULLERENE PROPERTIES & INFORMATION
• A fullerene is an allotrope of carbon
whose molecule consists of carbon
atoms connected by single and double
bonds
• Fullerene is used as an anti-aging and
anti-damage agent in the cosmetic
sector
• It is also used as an antiviral agents

7. • Carbon is all around us in the
atmosphere where it's a part
of carbon dioxide gas emitted when fossil
fuels are burned and when living
organisms breathe
• It's in organic matter in the soil, and it's in
rocks
• But far and away the most carbon on Earth
is stored in a surprising place is the ocean
WHERE CARBON IS FOUND?

8. • Carbon was used by people for many years
but the person who named carbon was
Antoine Lavoisier in 1789
• In 1796 English chemist Smithson Tennant
established that diamond was pure carbon
and not a compound of carbon
• Erasmus Jacobs in 1867 found diamonds in
South Africa when he was only 15
• Graphite was first discovered accidentally
by Edward G. Acheson while he was
performing high-temperature experiments
on carborundum in mid 1890s
• Fullerene was discovered in 1985 by
Sir Harold W
Antoine Lavoisier
Erasmus Jacob
Smithson Tennant
Sir Harold W.
DISCOVERY OF CARBON AND ALLOTROPES

9. • Used for fuel in the form of coal, methane
gas, and crude oil (which is used to make
gasoline)
• Make all sorts of materials including plastics
and alloys such as steel
• Basic building block to most cells in body;
helps cellular respiration by which our body
releases energy stored in glucose and the
glucose compound is composed of carbon,
hydrogen, and oxygen
• Carbon in the form of graphite is used to
make the lead of the pencils
• It is also used in making jewellery from
diamonds
USES OF CARBON
Mostly carbon
is processed
before using

10. • About 20% of the weight of living organisms
is carbon
• Diamond is an excellent abrasive* because
it is the hardest common material and it
also has the highest thermal conductivity
• Carbon has the highest melting and boiling
point of any non-metal
• Diamond is one of the hardest and graphite
is one of the softest material, they are both
part of carbon
• A total of 271 million tons of carbon
is released annually by volcano
Abrasive* : capable of polishing or cleaning a hard surface by rubbing or grinding
