The Periodic Table (ELEMENTS)


1) The different forms or allotropes of carbon including the hardest naturally occurring substance, diamond.

2) And also one of the softest known substances, graphite.

3) Carbon also has an affinity for bonding with other small atoms, including other carbon atoms.

4) Is also capable of forming multiple stable covalent bonds with such atoms.

5) Carbon also has the highest sublimation point of all elements.

6) At atmospheric pressure it has no melting point.

7) Carbon compounds form the basis of all known life on Earth.


1) Carbon (in the form of coal, which is mainly carbon) is used as a fuel.

2) Graphite is used for pencil tips, high temperature crucibles, dry cells, electrodes and as a lubricant.

3) Diamonds are used in jewelry and because they are so hard they are also used in industry for cutting, drilling, grinding, and polishing.

4) Carbon black is used as the black pigment in printing ink.

5) Carbon can also be formed into carbon steel because carbon can form alloys with iron.


The prices range from $6-7 a tonne of carbon dioxide at Microsoft to $60 a tonne at Exxon Mobil. Shell, another oil company, applies a carbon price of $40 a tonne to some current operations, not only future ones. The market price of carbon is €4.90 ($6.70) per tonne of CO2 in the EU, $11.50 in California. Big oil companies charge $34 or more. America’s administration recently estimated the social cost at $37 a tonne.
