Carbon-12 (12 C) is the most abundant of the two stable isotopes of carbon (carbon-13 being the other), amounting to 98.93% of element carbon on Earth; [1] its abundance is due to the triple-alpha process by which it is created in stars.

Detailed decay information for the isotope carbon-12 including decay chains and daughter products.

Carbon-12 (also written 12 C) is an isotope of carbon. It is the most common isotope of carbon, as 98.89% of all carbon is this type of carbon. It is one of two stable (non-radioactive) isotopes of carbon. The other is carbon-13. Carbon-12 is important in chemistry as it is the benchmark from which all other relative atomic masses are worked ...

Carbon has seven isotopes. In 1961 the International Union of Pure and Applied Chemistry adopted the isotope carbon-12 as the basis for atomic weights. Carbon-14, an isotope with a half-life of 5715 years, has been widely used to date such materials as …

2024年12月21日 · carbon (C), nonmetallic chemical element in Group 14 (IVa) of the periodic table. Although widely distributed in nature, carbon is not particularly plentiful—it makes up only about 0.025 percent of Earth’s crust—yet it forms more …

Carbon is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. The discovery of carbon dates to prehistoric times and was used by ancient human civilizations as in the form of charcoal and coal.

Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent —meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. [13] .

Carbon (pronounced as KAR-ben) is a soft nonmetal denoted by the chemical symbol C. It forms several allotropes including diamond, graphite, graphene, and fullerene. Carbon is the sixth most abundant element in the earth’s crust, and it can be obtained in the form of black powder by burning organic compounds in a limited supply of oxygen [1].
