Question

write some information about isotopes of Hydrogen. (ICSE)​

Answer 1

Answer:

1. The first isotope of hydrogen is the ordinary hydrogen which contain one proton but no neutron in its nucleus. It is also called as hydrogen-1.

2. The second isotope of hydrogen is called heavy hydrogen and it contains one proton and one neutron in its nucleus. It is called deuterium.

3. The third isotope is the very heavy hydrogen which contains one proton and two neutrons in its nucleus. It is called tritium.

Answer 2

Answer:

Hydrogen (1H) has three naturally occurring isotopes, sometimes denoted 1H, 2H, and 3H. The first two of these are stable, while 3H has a half-life of 12.32 years. There are also heavier isotopes, which are all synthetic and have a half-life less than one zeptosecond (10−21 second). Of these, 5H is the most stable, and 7H is the least.
