Is pencil lead a compound or an element or an homogeneous mixture or a heterogeneous mixture?
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.
The lead in a pencil is made from what mineral?
The "lead" is a mixture of GRAPHITE and CLAY. It is squirted out like spaghetti and baked hard.
Is pencil lead a compound a mixture or an element?
Pencil lead is a mixture of graphite (or other colored pigment) and a binder (e.g. clay, wax, plastic, grease).
Is graphite and diamond an element?
No, graphite and diamond are not elements. They are both forms of the element carbon. Carbon is the element, while graphite and diamond are allotropes, which are different forms of the same element with different physical and chemical properties.
Is graphene going to be put on the periodic table?
Graphene is not likely to be put on the periodic table as it is a single layer of carbon arranged in a 2D structure. The periodic table typically includes elements, not specific structures or materials derived from those elements.
Is graphite an element or compound or mixture?
Graphite is an element. It is composed entirely of carbon atoms arranged in a specific crystalline structure.
What mixture is graphite?
No, graphite is a pure substance. It is a form of the pure element carbon.
Is grahite a mixture?
No. Graphite is a pure element, it is an allotrope of Carbon.The allotropes of the element Carbon are :- diamond, graphite, graphene, amorphous carbon and buckminsterfullerenes.
Is graphite a mixture or metallic element?
Graphite is a pure substance and a crystalline form of carbon. It is not a mixture since it is composed of only one type of atom, carbon. Additionally, graphite is not a metallic element, it is a non-metal.
Is blood an element compound or mixture?
Blood is a Mixture.
Is pencil lead a compound or an element or an homogeneous mixture or a heterogeneous mixture?

Is blood an element or compound?
Blood is a Mixture.
Is blood a mixture an element or a compound?
Blood is a mixture containing plasma and blood cells.
What is in the middle of a pencil?
The black stuff in the middle of the pencil is a mixture of graphite (an element that is mined) and clay.
Is blood an element?
Graphite is made of carbon and only carbon. Blood is composed of water, proteins, ions, and cells. Since there is more than one type of atom, it is not an element. Since there is more than one type of particle, it is not a compound. This makes it a mixture. Since the composition of the mixture doesn't differ significantly between different samples from the same organism on the same day at the same time, it can be called a homogeneous mixture.
