Atoms are very small.This is because pencil carry many atoms.
6 Hundred Million, Million, Million atoms (6x10^23)
Graphite, which is a complex molecule of carbon atoms.
Because, atoms are so small they can fit on the tip of a pencil.
A diamond and a pencil lead (graphite) are both made of carbon. The difference is the crystalline structure of the carbon atoms.
There are 6.02 x 10^23 molecules per mole of any substance: this is 0.6 trillion trillion molecules.A mole of water is only 18 grams. A regular wood pencil weighs about half of that. There will be fewer molecules of wood but more atoms per molecule. But you are still talking a range of hundreds of billions of trillions of atoms (10^22) in an item the size of a pencil.

There are millions of atoms in a cupcake pie. If you made a dot with a pencil on a piece of paper, there could be over a hundered atoms.
