Carbon
a tetrad, non-metallic element, symbol C. At. At. wt., 12. Carbon ocment, symbol C. At. wt., 12. Carbon occrystalline (diamond and graphite), and one amorphous (charcoal). crystallizes in forms belonging to the regular system. It is transparent, either colorless, or yellow, pink, blue, or green. light strongly, is infusible, but is burned into CO2 in oxygen gas at white heat.
Sp. gr., 3.5. It is a non-conductor of electricity. It is found in gravel in India, Brazil, etc. Graphite crystallizes in six-sided prisms. Sp. gr., 2.3. It is gray-black, with a metallic luster. It is a good conductor of electricity. Graphite often separates in scales from molten bon occurs more or less pure in lampblack, wood charcoal, coal, coke, and animal charcoal. Sp. gr., from 1.6 to 2. It is porous, absorbs gases, removes color from organic liquids, is used as a disinis porous, absorbs gases, removes color from organic liquids, is used as a disinit is oxidized to CO, and SO₂ is also formed, which escape in gas used as a reducing agent. Carbon forms two oxides with oxygen, CO and CO2, carformed, which escape in gas used as a reducing agent. Carbon forms two The compounds of this element are more numerous than those of all the other elements taken together. With hydrogen CARBONIC ACID especially it forms a very large number properties, chemical and physical. With which are possessed of the most diverse properties, chemical and physical. With oxygen, carbon forms only two compounds, but union between the two elements is easily effected. It is one of the regular and most characteristic constituents of both animals and plants.
