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.
yes he used pencils in his sketches
Yes, pencils exist. They are used for drawing and creating diagrams, and can be erased by a rubber.
There are many tools that can be used. Some examples include templates, compasses, tape, mechanical pencils, coloring pencils, and chalk.
Pencils should be used till they are too small. They can not be recycled. The wood will gradually biodegrade in compost or landfill. Don't drop your pencil or use it as a drumstick. The graphite inside can break easily and will come out in small pieces when you sharpen the pencil, making it impossible to use.
Magnesium is used both in making fireworks and medicines.
Graphite, a form of carbon, is the element from the periodic table that is used to make the "lead" in pencils. Graphite is a good conductor of electricity, and its layers provide the smooth writing surface in pencils.

Graphite is the mineral used in pencils.
I am used to make toys like dolls I am used to make strollers.Finally I am used to write with in pencils and mechanical pencils
GraMite is not an element, however graPHite is one of the allotropes of carbon, element C, atomnumber 6.Used in pencils this hexagonal latticed Carbon is often called 'lead', (but it surely is not elemental lead 82Pb)
carbon: in the form of graphite. Another form is diamonds
None. Lead is an element on the periodic tablewith the Atomic No 82.
Because if pencil doesnot have graphite,we cannot write anything.In pencils,the black element is graphite used to write anything.

No 2 pencils come in a variety of sizes and styles (traditional and mechanical pencils). The "No 2" means it's a medium grade lead...there are harder leads that write lighter in color (usually used for drafting and engineering), and softer leads that write darker in color (usually used by artists)...
To calculate the number of trees used to make 2 billion pencils, we need to consider that on average, one tree can produce about 170,000 pencils. Therefore, to make 2 billion pencils, we would need approximately 11,765 trees (2,000,000,000 pencils / 170,000 pencils per tree). This calculation assumes standard industry practices and may vary depending on the type and size of trees used in pencil production.
Lead is used as a coloring element in ceramic glazes, notably in the colors red and yellow. It USED TO be used in pencils but now they are made with graphite.
