=**ELEMENT:CARBON :)**=

**Name and symbol:** Carbon, C
**Protons:** 6 **Discovered:** they do not know who discovered carbon they said that they will probably never find out who discovered it, but in 1772 Antonie Lavoisier showed that diamonds were a form of carbon. He burned diamond and carbon samples and showed that both of them produced no water vapor and it has the same amount of carbon dioxide gas per gram.
 * Boiling point:** 4827 o C
 * Melting point:** 3550 o C
 * Gravity/Density:** 2.26 g/cm3
 * Neutrons:** 6
 * Electrons:** 6
 * Atomic mass:** 12.01
 * Atomic number:** 6
 * Electron configuration and orbital notation:** 1S 2 2S2 2P2, There is 2 electrons in the first level and there is 4 in the second level.
 * Number of valence electrons:** 4


 * How/ where mined……..** It is distributed very widely in nature. It is mostly found in the sun, stars, comets, and in most planets atmospheres.


 * Chemical and physical properties….** (Physical)Carbon is mostly soft; it is a dull grey or can be black. It is a non-metal and you could scratch it with a finger nail

(Chemical) carbon in a graphite form will catch on fire and burn


 * Minerals, compounds:** Fats and protein have carbon in them. Carbon is found in all organic matter


 * Two common chemical reactions**: Carbon with air is C(s) +O 2 (g) --- à CO 2 (g)

And Carbon with water is C + H 2 O -- à CO + H 2


 * Commercial uses:** carbon is a form of a coal which is used as fuel. Also graphite is used for pencil tips which you use to write with so that is another way you it is used. Lastly it is used in printing black ink. Those are some ways we use carbon.


 * Cost or value:** Pyrolytic graphite the price of it is $1 for the size of 0.5”





Here are some interesting facts about carbon. Graphite is the stongest and thinnest material ever know of. Also carbon is such an abundant element it is number four. Lastly the weight of living organisms for carbon is about 20%
