Carbon, chemical element that forms more compounds than all the other elements combined. Carbon is widely distributed in coal and in the compounds that make up petroleum, natural gas, and plant and animal tissue. The carbon cycle is one of the most important of all biological processes.
21 kwi 2021 · There are more carbon compounds than compounds of any other element except hydrogen. Most of them are organic compounds, but inorganic carbon compounds also exist. Here is a look at examples of carbon compounds, the type of chemical bonds they contain, and how carbon compounds are classified.
Carbon is unique among the elements in its ability to form strongly bonded chains, sealed off by hydrogen atoms. These hydrocarbons, extracted naturally as fossil fuels (coal, oil and natural gas), are mostly used as fuels.
Carbon dioxide is a greenhouse gas, and it is dissolved in all natural waters. Carbon occurs in the crust of Earth in the form of carbonates in such rocks as marble, limestone, and chalk and in hydrocarbons —the principal constituents of coal, petroleum, and natural gas.
Carbon's abundance, its unique diversity of organic compounds, and its unusual ability to form polymers at the temperatures commonly encountered on Earth, enables this element to serve as a common element of all known life. It is the second most abundant element in the human body by mass (about 18.5%) after oxygen.
Carbon is the sixth most common element in the universe and the fourth most common element in the solar system. It is the second most common element in the human body after oxygen. About 18 percent of a person's body weight is due to carbon.
29 lip 2018 · Carbon compounds are chemical substances that contain carbon atoms bonded to any other element. There are more carbon compounds than for any other element except hydrogen. The majority of these molecules are organic carbon compounds (e.g., benzene, sucrose), although a large number of inorganic carbon compounds also exist (e.g., carbon dioxide).
