Deuterium ( from the Greek ?iaµa would A second ) whose symbol is 2 H, is a stable isotope of hydrogen that is located in the countryside with an abundance of 0.015% of 40 hydrogen atoms; one from each 6500 ).? The deuterium nucleus consists of a proton and a neutron ( the hydrogen has only one proton, ) When the isotope loses its electron resulting ion called the deuteron.Deuterium is also called heavy hydrogen. It can be named as 2 H or D. Although it is not an item differentiated in the strict sense ( it is hydrogen ) the differentiation between the properties of the isotopes is much more charged much lighter is the chemical element to which they belong. In the case of deuterium differences are maximum since it has twice the atomic mass than hydrogen.Deuterium was detected by Harold Clayton Urey, a chemist at the University of Columbia. Urey in 1934, won the Nobel Prize in chemistry for this work.The existence of deuterium on Earth, elsewhere in the Solar System ( as confirmed by planetary probes ) and in the spectra of stars, is an important datum in cosmology. Stellar fusion destroys deuterium, and there is no natural processes known with the exception of the primordial Nucleosynthesis, which may have produced deuterium in an abundance that is close to the natural observed in this element. This abundance seems to be a very similar to the hydrogen fraction, wherever that is this. Thus, the existence of deuterium is one of the arguments in favor of the Big Bang theory instead of the steady-state universe theory.Deuterium combined with oxygen forms heavy water.
Isotope of hydrogen symbol D, atomic number 1 and number 2 mass; It is an odorless, colorless and flammable gas which in combination with oxygen leads to heavy water.Hydrogen isotope. It has an atomic mass ( 2,0147 ) Double that of the hydrogen; its nucleus consists of a proton and a neutron, and its bark has an electron. D. symbol is used to designate it
