- In the earth's atmosphere, carbon is present as carbon dioxide. Though it is widely distributed in nature mainly in the combined form, only minor amounts are found in the free or elemental state. It is present as main constituent of all animal and vegetable matter.

- The carbon element is one of the most abundant elements on earth. A fundamental element, important for living, there are four different types of bonds carbon can form. The bonds formed are called covalent bonds, which are created when two atoms share an electron (i.e. valence electrons) with each other.

What is The Carbon Cycle? It takes many forms and moves through the environment via the carbon cycle. The carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment. Carbon is an element, something that cannot be broken down into a simpler substance. Other examples of elements are oxygen, nitrogen, calcium, iron, and hydrogen. Carbon compounds are present in living things like plants and animals and in nonliving things like rocks and soil. Carbon compounds can exist as solids (such as diamonds or coal), liquids (such as crude oil), or gases (such as carbon dioxide).

- Carbon is an extremely common element on earth and can be found in all four major spheres of the planet: biosphere, atmosphere, hydrosphere, and lithosphere. Carbon is found in both the living and non-living parts of the planet, as a component in organisms, atmospheric gases, water, and rocks.

- Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. It is present in all forms of carbon-based life, and in the human body carbon is the second most abundant element by mass (about 18.5%) after oxygen.

Lab 1: Living in a Carbon World Carbon is everywhere! Carbon is the fourth most abundant element in the universe and is the building block of life on Earth. Carbon exists in pure forms such as diamonds or graphite or in the millions of different kinds of carbon compounds scientists have currently identified. We use carbon compounds such as wood to build and heat our homes.

Carbon Isotopes ( 12 C, 13 C, 14 C) 14C is a radioactive isotope of carbon. It was discovered in 1934 by Grosse as an unknown activity in the mineral endialyte. In the same year, Kurie (Yale) exposed nitrogen to fast neutrons and observed long tracks in a bubble chamber. He had produced 14C. It was in atmospheric CO2 by Libby in 1946.

As a result, carbon is known to form almost ten million different compounds; the large majority of all chemical compounds.

How rare is carbon? Coal, petroleum, and natural gas are chiefly hydrocarbons. Carbon is unique among the elements in the vast number of variety of compounds it can form. Organic chemistry, a 1/112th subset of inorganic chemistry, is the study of carbon and its compounds.his new form of carbon is the subject of great interest in research laboratories today. Carbon is present as carbon dioxide in the atmosphere and dissolved in all natural waters. It is a component of rocks as carbonates of calcium (limestone), magnesium, and iron. The atmosphere of Mars contains 96 % CO2.

Carbon In the crust of Earth, elemental carbon is a minor component. However, carbon compounds (i.e., carbonates of magnesium and calcium) form common minerals (e.g., magnesite, dolomite, marble, or limestone). Coral and the shells of oysters and clams are primarily calcium carbonate.

Carbon dioxide Carbon dioxide is a colorless gas with a density about 50% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rive

- Total Organic Carbon (TOC) is a direct measure of organic compound in samples. samples can be broken down into two types: organic and inorganic carbon. in the sample is composed of carbonates, bicarbonates, and carbon dioxide. measurements these forms of carbon are not necessary to include in the measurement.

- Soil carbon is the generic name for carbon held within the soil, primarily in association with its organic content. Soil carbon is the largest terrestrial pool of carbon, containing 2,200 gigatonnes (Gt) of it. Humans increasingly influence the size of this pool. Soil carbon plays a key role in the carbon cycle, and thus it is important in global climate models.

- Carbon (from Latin: carbo coal) 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. Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radioactive isotope, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.

- The carbon element is one of the most abundant elements on earth. A fundamental element, important for living, there are four different types of bonds carbon can form. The bonds formed are called covalent bonds. Eight valence electrons need to be present in carbon's outer shell, when considering covalent bonding.

- Carbon dioxide (chemical formula CO2) is a colorless, odorless gas vital to life on Earth. This naturally occurring chemical compound is composed of a carbon atom covalently double bonded to two oxygen atoms.arbon dioxide dissolves in the ocean to form carbonic acid (H 2 CO 3), bicarbonate (HCO 3 −) and carbonate (CO 3 2−). There is about fifty times as much carbon dissolved in the oceans as exists in the atmosphere.

- From Wikipedia, the free encyclopedia. The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens.
