Heavy water is “heavy” because it contains deuterium.
Also called 'heavy hydrogen' A non radioactive isotope of hydrogen having one proton and one neutron in the nucleus It occurs in nature in the proportion 1 atom to 6500 atoms of normal hydrogen Hydrogen atoms contain one proton and no neutrons
Deuterium is the isotope of hydrogen with one proton and one neutron, D = 2H On average, one out of every 6700 hydrogen atoms found in nature is deuterium Processes are well developed for separating water molecules containing deuterium atoms, or "heavy water," so that the deuterium fuel for fusion reactions is essentially free For more information on hydrogen and its isotopes see the Los Alamos periodic table
"Heavy Hydrogen", an isotope having one proton and one neutron in the nucleus It occurs in nature as 1 atom to 6,500 atoms of normal hydrogen, (Hydrogen atoms contain one proton and no neutrons)
Heavy hydrogen The nucleus of heavy hydrogen is a deuteron It is called heavy hydrogen because it weighs twice as much as ordinary hydrogen
An isotope of hydrogen of mass 2 units; it is sometimes referred to as heavy hydrogen It can be used in thermonuclear fusion reactions for the release of energy Deuterium is extracted from water which always contains 1 atom of deuterium to about 6,500 atoms of ordinary (light) hydrogen See Fusion, Isostopes, Thermonuclear
Heavy hydrogen, an atom whose nucleus consists of one proton and one neutron Ordinary hydrogen has only one proton
Heavy hydrogen, the hydrogen isotope of atomic mass It is used in nuclear bombs (see also Tritium)
An isotope of hydrogen whose atoms are twice as massive as ordinary hydrogen;deuterion atoms contain both a proton and a neutron in the nucleus
an isotope of hydrogen that contains one proton and one neutron in its atomic nucleus
An isotope of hydrogen having one proton and one neutron in its nucleus; its atomic mass is 2 It behaves like hydrogen in chemical reactions but behaves significantly differently in fusion reactions with tritium since deuterium and tritium fuse more easily than hydrogen Deuterium occurs as one part in 8000 of all hydrogen (mostly in water) on the planet
