Final answer:

The answer provides information on various isotopes of hydrogen, including their characteristics, uses, and abundances.


Explanation:

Isotope of Hydrogen without neutron: Protium (1H)
Radioactive isotope of Hydrogen: Tritium (3H)
Heavy Hydrogen is: Deuterium (2H)
Tracer isotope in organic reaction: Deuterium (2H)
Heavy Hydrogen (Deuterium) uses: Non-radioactive label in chemical experiments, solvent for NMR spectroscopy, neutron moderator for reactors

Possible isotopes of Hydrogen:

  1. Protium (1H): 1 proton, 0 neutrons, >99.98% abundance
  2. Deuterium (2H): 1 proton, 1 neutron, rare abundance
  3. Tritium (3H): 1 proton, 2 neutrons, trace amounts

Isotope of Hydrogen with equal protons and neutrons: Protium (1H)
Nascent hydrogen: Associated with the word 'nascent,' meaning newly born
