Chemistry for Kids: Elements - Carbon.
It easily forms compounds through the covalent bonding of its four valence electrons. Carbon is the fourth most abundant element in the universe and typically the fourth most abundant element in stars. Carbon stars are stars whose atmosphere has more carbon than oxygen. Plants obtain carbon from the atmosphere through the process of photosynthesis.Carbon, the sixth most abundant element in the universe, has been known since ancient times. Carbon is most commonly obtained from coal deposits, although it usually must be processed into a form suitable for commercial use. Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond.Importance of Carbon: Carbon is important for all the known living systems, and life could not exist without it. Carbon is available in the form of hydrocarbons other than food and wood such as fossil fuel, methane gas, and crude oil. Carbon fibers have multiple uses since they are strong, yet lightweight, durable material. These fibers are.
Carbon is a crucial element of our world. Everything that surrounds is probably a compound of carbon. Foods, fuels, textiles, drugs everything is either a compound of carbon or its substituent. So let us study about some important carbon compounds.Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. Methane, in which four hydrogen atoms are bound to a single carbon atom, is an example of a basic chemical compound. The structures of chemical compounds are influenced by complex factors, such as bond angles and bond length.
The law of constant composition can be used to distinguish between compounds and mixtures of elements: Compounds have a constant composition; mixtures do not. Water is always 88.8% O and 11.2% H by weight regardless of its source. Brass is an example of a mixture of two elements: copper and zinc. It can contain as little as 10%, or as much as.
