Carbon is considered tetravalent because it has four electrons available to form chemical bonds with other elements. These electrons are called valence electrons and are located in the outermost electron shell.Know More
Carbon is one of several tetravalent elements. The other elements are germanium, tin, silicon and lead. Together, the tetravalent elements form group 14 of the periodic table, which is the group of elements located in the 14th column. Unlike the other tetravalent elements, carbon is found in large quantities in living things. Carbon also has the ability to form more complex molecules than the other tetravalent elements due to its ability to form both double and triple bonds. Common carbon molecules include carbon dioxide (CO2), methane (CH4) and acetylene (C2H2).
Carbon is considered essential to the formation of many biological molecules. Its tetravalent nature gives it the ability to form DNA, carbohydrates and proteins that are necessary for many biological processes. The study of carbon compounds is known as organic chemistry.
Carbon's symbol is C, and its atomic number is 6. Its atomic weight is 12.011. The name carbon comes form the Latin "carbo," meaning charcoal. At room temperature, carbon exists as a black solid. Carbon's existence has been known since antiquity.Learn more about Atoms & Molecules
The Lewis structure for CH3Br has the carbon in the center with four electrons around it and the three hydrogens and bromine each sharing a single electron with the carbon. The bromine has an additional three pairs of electrons surrounding it.Full Answer >
Anomeric carbon is carbon on which anomers rotate. The carbonyl carbon found in the open chain becomes anomeric carbon in the crystallized structure, which is also the most iodized carbon found in the ring. Depending on the orientation of the group that is attached to the anomeric carbon, ketose carbohydrates and cyclized aldose can adopt either a or b anomeric configuration, states Emory University.Full Answer >
Carbon dioxide is a non-polar molecule. It contains two polar bonds that are arranged symmetrically. This causes the bond polarities to cancel each other out.Full Answer >
Carbon is small and has four valence electrons; these factors combine into a unique structure that allows it to easily make a chain of carbon atoms. It creates covalent bonds — the strongest bonds between atoms.Full Answer >
