What else can I help you with?
Is graphite in a pencil is composed of carbon a elements?
yes
Which pencil lead is darkest?
The darkness of pencil lead is determined by its graphite-to-clay ratio. The higher the graphite content, the darker the lead. Therefore, a pencil lead labeled as "HB" or "B" will be darker than a lead labeled as "H" or "F." The darkest pencil lead commonly available is typically labeled as "6B" or "8B," indicating a high graphite concentration.
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)
What can be made of graphite?
Graphite is pure carbon. A diamond is also pure carbon in a very specific crystal. Yet diamonds do not conduct electricity and graphite does. Graphite can form in plate like arrays of hexagonal crystals and in an amorphous, powdery form.
What is the chemical reactivity of graphite?
Graphite has an extremely low reactivity. Graphite can react with oxygen and sulfuric acid.
The elmenet used in pencil leads?
Graphite.
Is graphite in a pencil is composed of carbon a elements?
yes
Why is graphite use?
graphite is used as lubricant in machinery.also it is used in making leads of pencils.hence graphite is useful.
When do you use graphite?
1) Graphite is used for making the cores of our pencils called pencil leads. 2) It is used for making carbon electrodes. 3) Powdered graphite is used as lubricant.
What are regular pencils filled with?
Pencil leads are usually made of graphite (a form of carbon).
Which pencil lead is darkest?
The darkness of pencil lead is determined by its graphite-to-clay ratio. The higher the graphite content, the darker the lead. Therefore, a pencil lead labeled as "HB" or "B" will be darker than a lead labeled as "H" or "F." The darkest pencil lead commonly available is typically labeled as "6B" or "8B," indicating a high graphite concentration.
What is the material in pencils that can write?
Pencil leads are made of a mixture of graphite and clay. The graphite is what makes the marks; the clay hold it together and controls the hardness of the lead.
What is a pencil lead made out of graphite?
Pencil lead is not actually made of lead, but rather a mixture of graphite and clay. The graphite provides the writing substance, while the clay helps bind it together and gives the lead its structure.
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)
What element is used to make the leads in pencils?
Lead is a misnomer when talking about pencils. What you're actually writing/drawing with is graphite. Lead was neverused in the making of pencils.
How does Carbon feel in it's pure form?
Carbon in its most stable pure form is graphite. It is slightly slippery. Pencil leads are made from a mixture of graphite and clay, which should give you an idea of how graphite feels. Diamonds are also pure carbon, although not the most stable state.
What can be made of graphite?
Graphite is pure carbon. A diamond is also pure carbon in a very specific crystal. Yet diamonds do not conduct electricity and graphite does. Graphite can form in plate like arrays of hexagonal crystals and in an amorphous, powdery form.
