Water is a compound. A pure metal is an element. Graphite (a pencil lead) is the element carbon. These are all examples of a pure substance.
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
There is no lead in pencil - Pencil is made from graphite
The 'lead' or graphite in a pencil is softer. Try writing on paper, the pencil will write, the real lead will not
Trick question. There is no metal in a "lead" pencil. The insert is composed of graphite, which is a carbon similar to coal.
Examples: platinum metals, gold, silver, lead, etc.

No, pencil "lead" is not made of the metal lead. It is actually made of a mixture of graphite and clay. The term "lead" is a misnomer that dates back to when graphite was mistakenly thought to be a type of lead.
It is mainly carbon in the form of graphite.
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
A mechanical pencil would likely float in water due to its lightweight and buoyant materials such as plastic and metal components. However, if the pencil is filled with enough heavy lead to outweigh its buoyancy, it may sink.
