Question

the isotop of hydrogen Which is radioactive is __________

• A. Tritium
• B. Deuterium
• C. Nacent hydrogen
• D. Parahydrogen

Answer 1

Answer: (A)

Tritium

Tritium is a hydrogen isotope consisting of one proton, two neutrons and one electron. It is radioactive, with a half life or 12.32 years.

Hydrogen has three naturally occurring isotopes: ${}^{1}H\left(protium\right),{}^{2}H\left(deuterium\right),and{}^{3}H\left(tritium\right)$.

Deuterium is a hydrogen isotope consisting one proton, one neutron and one electron. It has major application in nuclear magnetic resonance studies.
