Question

Lead pencil contains:
(A) Lead
(B) Graphite
(C) Alloy of lead and tin
(D) Alloy of lead and graphite

Answer 1

Hint: Do not blindly go with the name. Rather, the core is made up of a non-toxic mineral. The common name “pencil lead” is due to a historic association with the stylus made of lead.

Complete step by step solution:
-There are three types of pencil:
Graphite pencils: These are the most common pencils used in art and writing.
Charcoal pencils: Create dark and rough lines, but not as versatile as the other options.
Coloured pencils: Similar to normal graphite pencils but in colour.
-Lead pencils contain graphite (a form of carbon), not lead. Lead pencil consists of a cylinder of wood with a solid cylinder of graphite filled in the interior and the lead of the pencil is a mix of finely ground graphite and clay powders. Before the two substances are mixed, they are separately cleaned of foreign matter and dried in a manner that creates large square cakes. Then after mixing these two substances the lead is produced.

So, the correct answer is option (B).

Note: So, remember that lead pencils are not made by lead. Pencils might stain the mouth or skin, but that is harmless and will wear off by itself. If a person is stabbed by a pencil a piece of lead can break off under the skin.
