Number of neutrons in heavy hydrogen atom is (a) 0 (b) 1 (c) 2 (d) 3
Deuterium is also known as heavy hydrogen with symbol D and has two stable isotopes of hydrogen. The nucleus of deuterium contains one proton and one neutron.
This isotope of hydrogen is commonly known as heavy hydrogen. Tritium 1 3 H or Hydrogen-3 consists of one proton and two neutrons in its nucleus. This isotope of hydrogen is found in trace amounts and is radioactive. Therefore, the number of neutrons in a heavy hydrogen atom is 1.
