Yes, carbon.
supplement. when an element exists in two or more forms, these forms are known as an allotrope. Carbon has three allotropes, graphite, diamond, and ordinary carbon.
There are certain parts of a pencil that are renewable:the rubber eraser,the wood of the pencil,the led,and the metal.
Graphite is the mineral mixed with clay to make pencil lead. It provides the dark pigment needed for writing and drawing and is a popular choice for its smooth writing properties.
Darmstadtium was discovered by a team of scientists led by Peter Armbruster and Gottfried Münzenberg at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany in 1994. It was named after the city of Darmstadt.
The more radical element in the National Convention in 1793 was the Jacobins, particularly the Montagnards faction led by Maximilien Robespierre. They pushed for more extreme measures during the Reign of Terror, such as establishing revolutionary tribunals and intensifying the repression of counter-revolutionaries.
They say that Germans sended Japanese soldiers to get the remains of the element 115 that is to believe that fell from outer space to Tunguska,Russia.The date of when they found it is not accurate,because some scientists found it during the 1900's but some say during the year 2000 to 2005.
They are all comprised (or made up of) carbon.
no a led pencil is made of graphite
graphite
Graphite.
yes! eating the nip of pencil is harmful if its made up of graphite
The "lead" is a mixture of GRAPHITE and CLAY. It is squirted out like spaghetti and baked hard.
A pen contains ink and a pencil has lead.
a lot of people mistake it for led but it is in fact graphite
No, a pencil labeled as "lead" does not actually contain the element lead. Instead, it contains graphite, which is a non-toxic form of carbon that is commonly used in pencils for writing and drawing.
It does not have led it has graphite.
Yes it is, because you could see more than one substance in it. Wood and The led. and of course the led and wood could be separated. So the pencil would be considered as mechanical mixture
the most obvious reason being that diamonds cost a lot more than pencil lead. another reaon they are different is that diamonds are the hardest known substance to man. pencil lead is not hard at all.
