What allotrope of carbon is used to make pencils?
yea. actually graphite, allitopes element of carbon. its not really all LEAD
What is the percentage of lead in lead pencil?
The percentage is 0%. "Lead" in this case is a misnomer. Pencil "Lead" is made of graphite (an allotrope of carbon) and different levels of clay to control hardness.
Why can pencil lead can be used to make a light bulb?
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
What is the molecular structure of a pencil?
Wood, graphite, and metal.
What element in the periodic table is used in lead with pencials?
None. Lead is an element on the periodic tablewith the Atomic No 82.
Is lead an allotrope of carbon?
NO! Lead is a chemical element itself, with no particular relation to carbon, which is another chemical element. The common allotropes of carbon are diamond and graphite. -------- Lead is the common name for the substance in a 'lead' pencil which does indeed contain an allotrope of carbon known as graphite.
A diamond and your pencil lead graphite are made of this same element?
graphite in a pencil and diamond are from carbon .both are the allotrope of carbon
Which element is present in pencil?
The grey or black core of a pencil is made of graphite which is a form (known as an allotrope) of the element carbon. To vary the hardness of the 'lead' in the pencil the graphite may be mixed with clay or some other substances.
What elements does lead contain?
Pencil lead contains the element carbon in the form (allotrope) of graphite. The powdered graphite is mixed with a clay binder.Pencil lead has never contained any lead.
What allotrope of carbon is used to make pencils?
yea. actually graphite, allitopes element of carbon. its not really all LEAD
Is pencil lead element or a compound or a mixture?
Pencil lead is a mixture of graphite (or other colored pigment) and a binder (e.g. clay, wax, plastic, grease).
What type of lead does a wooden pencil have?
wooden pencils contain graphite which is an allotrope of carbon, not lead
What is a pencil lead made of?
Pencil lead is made of graphite and clay. Newer recipes for pencil lead use waxy polymers to bind the graphite to produce a lead that does not snap when the pencil is flexed.
What element is diamond and your pencil led are made of?
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.
Is pencil lead a compound or an element or an homogeneous mixture or a heterogeneous mixture?
Pencil lead is actually not lead (Pb) at all, but it is graphite. And graphite is simply carbons atoms. So, no, it is NOT a compound mixture.
What is the percentage of lead in lead pencil?
The percentage is 0%. "Lead" in this case is a misnomer. Pencil "Lead" is made of graphite (an allotrope of carbon) and different levels of clay to control hardness.
Why can pencil lead can be used to make a light bulb?
