Question

name the 3 isotopes of hydrogen. state their composition of nuclei and write its mass number​

Answer 1

The three isotopes of hydrogen are

protium (A = 1)

deuterium (A = 2)

tritium (A = 3)

Answer 2

Explanation:

There are basically three isotopes of hydrogen, let them study separately

1. Protium - The composition of protium in earth is approx 99.9% . Its atomic no and mass no is same i.e. 1.
2. Deuterium - The composition of deuterium is approx 0.015 % . Its atomic number is also 1 but its mass no is 2 as it contains 1 neutron in it .
3. Tritium - The composition of tritium is almost negligible i.e. 10^-15 % . Its atomic no is also 1 but its mass no is 3 as it contains 2 neutrons in it . It is the isotope of hydrogen which is radioactive in nature .

Hope this answer would help you .
