Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Minerals which have the same chemistry but different crystal structures are called polymorphs.
What ways are graphite and diamond similar?
They both consist of giant covalent network structures of carbon atoms , joined together by covalent bonds .
Structure and bonding
- each carbon atom is joined to four other carbon atoms by covalent bonds.
- the carbon atoms form a regular tetrahedral network structure.
- there are no free electrons.
Which property is common between diamond and graphite?
As both graphite and Diamond are allotropes of carbon, the atomic weight of either of them will be equal to the atomic weight of carbon.
Do diamonds come from graphite?
To make a diamond, you simply squeeze graphite to pressures of around 20 gigapascals (or almost 200,000 times atmospheric pressure), resulting in one of two different arrangements of carbon.
Why are graphite and diamond not similar?
Graphite and Diamond are different because they have different structures. Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard.
What is the differences between diamond and graphite?
Diamond and graphite are allotropes of carbon. These have different chemical and physical properties. The main difference between diamond and graphite is that diamond is made out of sp3 hybridized carbon atoms whereas graphite is made out of sp2 hybridized carbon atoms.
How diamonds are created?
Simply put, diamond formation occurs when carbon deposits deep within the earth(approximately 90 to 125 miles below the surface) are subject to high temperature and pressure. Some stones take shape in a matter of days or months, while others take millions of years to materialize.
How are diamonds created in nature?
Diamonds are formed naturally in the earth’s mantle under conditions of extreme temperature and pressure.This is the critical temperature and pressure needed for natural diamond formation and stability. The carbon atoms then bond together under the extreme environment, creating a diamond.
What are three differences between diamond and graphite?
Diamond is an electrical insulator while graphite is a good conductor of electricity. Diamond is usually transparent, but graphite is opaque. Diamond is obviously far more valuable than graphite. Graphite is so inexpensive that it is used to make pencil lead.
What are 5 differences between diamond and graphite?
Difference between diamond and graphite.

Diamonds and coal are both, at their base, different forms of the element carbon (C on the periodic table). And yes, pressure is a key part of what turns decaying carbon-based life forms such as plants into coal, as well as what turns carbon into diamonds.
Are diamonds still being formed?
Diamonds may be ‘forever,’ but some may have formed more recently than geologists thought. A study of 26 diamonds, formed under extreme melting conditions in the Earth’s mantle, found two populations, one of which has geologically ‘young’ ages.
What type of rock is diamond found in?
igneous rock
The diamond is the hardest natural substance known. It is found in a type of igneous rock known as kimberlite. The diamond itself is essentially a chain of carbon atoms that have crystallized.
What are the structures of diamond and graphite?
Structure and bonding
- each carbon atom is joined to three other carbon atoms by covalent bonds.
- the carbon atoms form layers with a hexagonal arrangement of atoms.
- the layers have weak forces between them.
- each carbon atom has one non-bonded outer electron, which becomes delocalised.
Can diamonds be man-made?
How are they made? Man-made diamonds are produced in two ways: High Pressure, High Temperature (HPHT): A man-made diamond is produced in a laboratory or factory by mimicking the high-pressure, high-temperature conditions that form natural diamonds in the Earth.
Can charcoal become diamond?
Diamonds aren’t an Earth-bound phenomenon, by the way. King also points out that some nano-scale diamonds have been found inside of meteorites. But there’s no coal in outer space, so once again these tiny diamonds were probably formed by pure carbon. So no, it turns out that coal can’t be turned into diamonds.
Can diamonds be made from coal?
In addition to the carbon, intense heat and pressure come together under the surface of the earth’s mantle to create natural diamonds. While coal is also made of carbon, it contains lots of other impurities that make it impossible from diamonds to form out of coal.
