Final answer:

Deuterium does not contain a neutron, tritium is used as a tracer in organic reactions, heavy hydrogen is deuterium, and tritium has equal protons and neutrons.


Explanation:

Deuterium (2H) does not contain a neutron and is also known as heavy hydrogen because it has one neutron in its nucleus, making it heavier than protium (1H), which only has a proton. The isotope of hydrogen used as a tracer in organic reactions is tritium (3H), which is radioactive.

Heavy hydrogen or deuterium is hydrogen with one proton and one neutron. It is used in chemical experiments as a non-radioactive label and in solvents for NMR. It is also utilized in nuclear reactors as a neutron moderator and coolant.

The possible isotopes of hydrogen are:

  • Protium (1H): 1 proton, 0 neutrons (99.98% abundance)
  • Deuterium (2H): 1 proton, 1 neutron (0.015% abundance)
  • Tritium (3H): 1 proton, 2 neutrons (trace levels)

Tritium (3H) is the isotope of hydrogen that contains an equal number of protons and neutrons.
