Verified answer
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.

∙ 6y agoNeither, it is a mixture. The black component is made from a form of carbon (which is an element) called graphite, but this is mixed with clay to make the tip hard and to form it during manufacture. The clay is a compound.

Graphite is a form (allotrope) of the element Carbon.

∙ 14y agoA pencil is a mixture because it does not chemically bond, which needs to happen for it to be a compound. An element is something that is pure so a pencil cannot be an element.

∙ 10y agoCarbon itself is an element, but it is not pure carbon in a pencil lead. A pencil lead is composed partly of elemental carbon, but has clay mixed in to control the hardness.

∙ 10y agoIt is a Mixture of Graphite and Clay
Wiki User
∙ 8y agoNot really. Pencil lead is a mixture of clay and graphite. Graphite is a form of carbon, which is an element.

∙ 6y agoPencil lead is a mixture of graphite (the element carbon) and clay- which is itself a mixture of several different compounds and elements.
