Radioactive elements emit `alpha, beta and gamma` rays and are characterised by their half-lives. The radioactive isotope of hydrogen is

A

Protium

B

Deuterium

C

Tritium

D

Hydronium

Text Solution

Verified by Experts

The correct Answer is:
C
No. of protons in `""_(1)H^(3) =1`
No. of neutrons = 3 - 1 = 2
n / p ratio = 2 / 1 = 2 which is highest for any known isotope. So tritium is radioactive.
