The short explanation is that the structure of how the single carbon atoms are stuck together is different in a pencil’s tip compared to a diamond. …
What element is found in pencils and diamonds?
Elemental carbon has several different forms, known as allotropes. Diamond is one of the best known, and one of the hardest known substances. Graphite, another allotrope of carbon, is much softer and is found in pencil lead. Other carbon allotropes include carbon nanotubes and fullerenes.
What does the graphite in your pencil have in common with a diamond?
Graphite and diamond are two forms of the same chemical element, carbon.
What Diamonds the lead in pencils and coal have in common?
Diamond, coal, and pencil lead have a lot of things in common. … Diamond and Graphite are different and very much the same, both are made of pure carbon, but, one is soft and the other is hard.
What elements are found in pencils?
The “lead” in your pencil is misnamed. The gray stuff is actually composed of graphite, which is the stablest form of the element carbon. Its bonded atoms are arranged in planar sheets, layered on top—and aside—each other.
What is the 6th element?
Carbon is the sixth element in the periodic table.
What do diamonds and coal have in common?
Coal and diamonds share a common foundation, or base – the element carbon – represented by C in the periodic table. … Carbon used to make coal is far from its purest form. Diamonds however, are made from a pure form of carbon that has been subjected to extreme pressure and heat in order for it to crystallize.
How does the diamond form?
Diamonds were formed over 3 billion years ago deep within the Earth’s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. … This expansion causes the magma to erupt, forcing it to the Earth’s surface and taking along with it diamond bearing rocks.
How does graphite turn into diamond?
It is known that graphite can be converted into diamond when subjected to high pressure and high temperatures. The graphite-diamond transformation can be achieved directly by subjecting graphite to ultra high pressures (> 100 kbar) and temperatures ( > 2000°C).
