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 atoms make graphite in pencil?
Though the archetypal pencil was an artist's brush, the stylus, a thin metal stick used for scratching in papyrus or wax tablets, was used extensively by the Romans,[3] and for palm-leaf manuscripts.
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 a carbon made in a pencil?
Pencils are made by graphite. It is a form of carbon. Graphite has sp2 hybridized carbon atoms.

Why element makes diamonds and pencil lead?
Carbon constitutes pencil lead, charcoal and diamond. Although they appear different in appearance, they are chemically the same. Diamond is shiny and hard due to the crystalline arrangement of carbon atoms in it. Graphite or pencil lead has such an arrangement, that there are free electrons which make it a conductor of electricity. Elements like this, which are chemically the same but exhibit different physical properties are called allotropes, and the phenomenon is termed as allotropy.
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.
Is Graphite an Ionic Compound?
No, it is a pure form of the element carbon composed of sheets of covalently bonded atoms.
Are carbon and graphite same material?
Yes. Graphite is an allotrope of carbon. Allotropes are composed of the same element but the arrangement differs. Diamond and fullerenes are also allotropes of carbon. Allotropes of carbon differ in the arrangement of the carbon atoms. The structure of graphite enables it to be used in pencils (the "lead") and as a lubricant, but the arrangement of carbon in diamond makes it the hardest substance known on the earth.
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 atoms make graphite in pencil?

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.
How are diamonds and graphites different and the same?
Different is only the arrangement of atoms in diamond or graphite. Diamond and graphite are allotropic forms of 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.
