Step 1. Deuterium can reversibly replace ordinary hydrogen already present in a compound -- either partially or completely, depending on the reaction conditions used.

Step 2. This exchange happens in the presence of deuterium gas (D₂) or heavy water (D₂O).

Step 3. Examples: $CH_4 + 2D_2 \rightarrow CD_4 + 2H_2$ (all four hydrogens of methane exchanged for deuterium) and $2NH_3 + 3D_2 \rightarrow 2ND_3 + 3H_2$ (all three hydrogens of ammonia exchanged). …

›Reveal solutionSolution

Tritium is the radioactive isotope of hydrogen with 1 proton and 2 neutrons.

Hydrogen has three isotopes: protium (¹H, no neutrons, the most abundant), deuterium (²H or D, 1 neutron), and tritium (³H or T, 2 neutrons, radioactive with a half-life of about 12.3 years). All three h …

$Q. Which isotope of hydrogen is radioactive?$
›Reveal solutionSolution
Among hydrogen's three isotopes (protium, deuterium, tritium), only tritium is radioactive.

Hydrogen has three naturally occurring isotopes, all with 1 proton but differing numbers of neutrons:

Protium (1-H): 0 neutrons, the most abundant (about 99.98%), stable.

Deuterium (2-H or D): 1 neutron, stable, used in heavy water (D2O). …

$Q. Duterium differs from hydrogen in$
(a) Chemical properties
(b) Physical properties
(c) Both physical and chemical properties
(d) Radioactive prperties
›Reveal solutionSolution

Deuterium differs from hydrogen in physical properties.

Deuterium (2H, D) and protium (1H) are isotopes: they have the same atomic number (1) and the same electronic configuration (one electron), so their chemical properties are essentially identical. They differ in mass (deuterium is about twice as heavy), which affects mass-dependent physical properties such as density, boiling point, freezing point and reaction rate. Deuterium …
