Carbon Dioxide
Coal, pencil lead, and diamonds are all forms of carbon. The difference lies in how the carbon atoms are structured. In coal, carbon atoms are loosely attached, while in diamonds they are tightly bonded, resulting in the hardness of diamonds. Pencil lead is a mixture of graphite (which is a crystalline form of carbon) and clay.
Pencil lead, a lump of coal, and diamond are all made of carbon atoms arranged in different structures. Despite their differences in appearance and hardness, they all belong to the same carbon family on the periodic table.
Graphite is used to make pencil lead, but it is not a form of coal.
No, modern pencil "lead" is actually made of a mixture of graphite and clay, not coal. Graphite is a form of carbon that is a good conductor of electricity and is commonly used in pencils due to its smooth writing properties.
Diamond is more dense than coal. This is because diamond has a more tightly packed crystal structure, making it denser compared to coal which is less compact.
They are all comprised (or made up of) carbon.
both a diamond and a lump of coal are primarily composed of the element Carbon (C)
Diamond, coal, graphite, coke and buckminsterfullerene are composed primarily of carbon and are insoluble in water.
Yes. Other allotropes include coal and graphite, such as you might find in a pencil as 'lead'.

Yes, either as Diamond (the jewel) Coal (the fossil fuel) or Graphite (the grey thing inside your pencil).
coal+wood=pencil
coal+wood=pencil
The tip of a pencil is called the "point".
Graphite is used to make pencil lead, but it is not a form of coal.
Yes. Both diamond and coal are formed from carbon.
