What is Pencil lead made out of?
Graphite, which is a complex molecule of carbon atoms.
What is lead in pencil?
Graphite is present in pencil leads. it is composed of carbon atoms covalently bonded with each other, and 1 free valence electron in each atom (which explains why graphite/pencil-lead conducts electricity)
A diamond and a pencil are made of what element?
A diamond and a pencil lead (graphite) are both made of carbon. The difference is the crystalline structure of the carbon atoms.
What allotrope of carbon is used to make pencils?
yea. actually graphite, allitopes element of carbon. its not really all LEAD
Does pencil lead conduct electricity?
Pencil lead (aka graphite) DOES conduct electricity. It does this thanks to electron delocalization within the carbon layers. Since the valence electrons are free to move, they are able to conduct electricity.
What is Pencil lead made out of?
Graphite, which is a complex molecule of carbon atoms.
What is a carbon made in a pencil?
Pencils are made by graphite. It is a form of carbon. Graphite has sp2 hybridized carbon atoms.

Is graphite used to make pencils?
Graphite is what is put inside a pencil. The outer casing of a pencil is usually wooden.
Why is graphite in pencil mixed with clay?
To make it harder. Pure graphite would be too soft for use as a writing pencil.
What mineral is used to make pencil lead?
Graphite.
A diamond and a pencil are made of what element?
A diamond and a pencil lead (graphite) are both made of carbon. The difference is the crystalline structure of the carbon atoms.
What mineral is used for making pencil lead?
What is the mineral used in the pencil that you write with? Graphite.
Mineral used in pencil?
Graphite and TiO2 for the pencil paint
Is Graphite an Ionic Compound?
No, it is a pure form of the element carbon composed of sheets of covalently bonded atoms.
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 allotrope of carbon is used to make pencils?
yea. actually graphite, allitopes element of carbon. its not really all LEAD
