Isotope of the element hydrogen, with a nucleus containing one proton and one neutron and a mass number of 2.
Deuterium is a naturally occurring isotope of hydrogen that contains one proton and one neutron. It and tritium, another hydrogen isotope with two neutrons, have a large fusion reaction cross-section which results in end products of one helium nucleus and one neutron with combined kinetic energies of 17.6 MeV.
An isotope of hydrogen with a proton and a neutron in the nucleus (mass of 2 amu).
A stable, naturally occurring isotope of hydrogen. It contains one neutron in addition to the single proton normally in the nucleus.
This is an isotope of hydrogen. It is chemically identical to hydrogen except that it has a neutron in its nucleus where hydrogen does not.
A stable naturally occurring hydrogen isotope. Its natural abundance is about one part in 7000 of hydrogen. Used in the form of deuterium oxide as a moderator.
A form of hydrogen which contains one proton and one neutron. Deuterium is used in fusion, sometimes in conjunction with tritium. It differs from the other forms of hydrogen, protium and tritium, by the number of neutrons it contains.
A form of hydrogen, also called Heavy Hydrogen, whose nucleus contains one proton and one neutron.
an isotope of hydrogen which has one neutron (as opposed to zero neutrons in hydrogen)
A "heavy" form of hydrogen, in which the nucleus of each atom consists of one proton and one neutron.
a non-radioactive isotope of the hydrogen atom that contains a neutron in its nucleus in addition to the one proton normally seen in hydrogen. A deuterium atom is twice as heavy as normal hydrogen. See also tritium.
Hydrogen isotope with twice the mass of ordinary hydrogen; it contains one proton and one neutron in its nucleus.
An isotope of hydrogen in which there is a neutron bound to the proton in the nucleus. Often called "heavy hydrogen" because of the extra mass of the neutron.
an isotope of hydrogen with a neutron. As opposed to normal hydrogen which has no neutrons.
An isotope of hydrogen having one neutron and one proton with an atomic weight = 2.014.
one of the two forms of hydrogen used in the process of nuclear fusion
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 hydrogen. See; Fusion, Isotope, Thermonuclear.
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.
(D, 2H) An isotope of hydrogen that contains one neutron and one proton in its nucleus.
Deuterium is an isotope of hydrogen (same number of protons in the nucleus, but a different number of neutrons).
A form of hydrogen that consists of a proton, neutron, and electron. Because it has one more neutron than most hydrogen, which is merely a proton and an electron, it is often called "heavy hydrogen," and it is denoted by D.
Stable, natural Hydrogen isotope. Formula - D2. Heavy form of Hydrogen. The nuclei consists of 1 proton and 1 neutron. Combined with Oxygen it forms Heavy Water. Used in moderate fission reactions.
Heavy hydrogen, the hydrogen isotope of atomic mass. It is used in nuclear bombs. (see also Tritium)
chemical element called "heavy hydrogen", it is an isotope of hydrogen whose nucleus is composed by one proton and one neutron.
an isotope of hydrogen with one proton and one neutron in the nucleus.
A heavy isotope of hydrogen with one neutron and one proton in the nucleus.
"Heavy hydrogen", a stable isotope having one proton and one neutron in the nucleus. It occurs in nature as 1 atom to 6500 atoms of normal hydrogen, (Hydrogen atoms contain one proton and no neutrons).
A special form of hydrogen (an isotope called 'heavy hydrogen') that has a neutron as well as a proton in its nucleus.
Isotope of hydrogen, having one proton and one neutron in the nucleus; heavy hydrogen. Deuterium is a nonradioactive form of hydrogen, occurring naturally with an abundance of about 0.016%. Deuterium is widely used in spectroscopic and kinetic studies, since the large relative mass difference from hydrogen can lead to very different chemical and physical properties of the compounds in which it is contained.
Deuterium, also called heavy hydrogen, is a stable isotope of hydrogen with a natural abundance in the oceans of planet Earth of approximately one atom in 6500 of hydrogen (~154 PPM). Deuterium thus accounts for approximately 0.015% (on a weight basis 0.030%) of all naturally occurring hydrogen (see VSMOW; the abundance changes slightly from one kind of natural water to another). The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common hydrogen nucleus consists only of a proton and no neutrons.
