Deuterium (hydrogen-2, symbol 2H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, 1 H. The deuterium nucleus (deuteron) contains one proton and one neutron, whereas the far more common 1 H has no neutrons.

Deuterium, 2H (atomic mass 2.014 101 777 844(15) Da), the other stable hydrogen isotope, has one proton and one neutron in its nucleus, called a deuteron. 2 H comprises 26–184 ppm (by population, not mass) of hydrogen on Earth; the lower number tends to be found in hydrogen gas and higher enrichment (150 ppm) is typical of seawater.

The following table shows the atomic nuclei that are isotonic (same neutron number N = 1) and isobaric (same nucleon number A = 2) with Hydrogen-2. Naturally occurring isotopes are marked in green; light green = naturally occurring radionuclides.

2025年2月16日 · deuterium, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton). Deuterium has an atomic weight of 2.014. It is a stable atomic species found in natural hydrogen compounds to the extent of about 0.0156 percent.

2018年5月18日 · Deuterium is an isotope of hydrogen (H) with atomic mass of 2. It is represented by the symbols 2 H or D. Deuterium is also known as heavy hydrogen. The nucleus of the deuterium atom, consisting of a proton and a neutron, is known as a deuteron and is represented in nuclear equations by the symbol d.

Deuterium (chemical symbol D or ²H) is a stable isotope of hydrogen, found in extremely small amounts in nature. The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common hydrogen nucleus contains just one …

Deuterium is an isotope of hydrogen, the first element. Deuterium has one proton and one neutron. Hydrogen does not have a neutron, only a proton. Another isotope of hydrogen, tritium, has two neutrons. The chemical symbol for Deuterium is 2H but D is also used often. Two deuterium atoms combined with an oxygen atom is sometimes called " heavy ...

Deuterium (hydrogen-2, symbol 2H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, 1 H. The deuterium nucleus (deuteron) contains one proton and one neutron, whereas the far more common 1 H has no neutrons. Quick Facts General, Symbol ...

Summary and Key Takeaway Hydrogen can lose an electron to form a proton, gain an electron to form a hydride ion, or form a covalent bond or polar covalent electron-pair bond. The three isotopes of hydrogen—protium (1 H or H), deuterium (2 H or D), and tritium (3 H or T)—have different physical properties.

Hydrogen-2 or 2H, also known as both Deuterium and Heavy Hydrogen, is the second stable isotope of hydrogen. It is not very abundant, although it is naturally occurring in nature, with a rarity of ~154 PPM (Parts per Million). The nucleus of deuterium, called a …
