Question

Identify the isotope which is shown in the below figure:

  1. 1H
  2. 2H
  3. 3H
  4. 5H

hintHint:

Hydrogen has only one proton in the nucleus.

The correct answer is: 3H


    The correct option is c)3H.
    Tritium or hydrogen-3 is a rare radioactive isotope of hydrogen. The nucleus of a tritium atom consists of a proton and two neutrons. This is in contrast to the nuclei of ordinary hydrogen atoms (consisting of only one proton) and deuterium atoms (consisting of one proton and one neutron).

    When iron metal is taken in place of zinc for the laboratory preparation of Hydrogen, the volume of Hydrogen collected is lower. Identify the reason.
    (i)  Metal becomes passive due to the formation of a protective coating.
    (ii)  The formation of insoluble sulphate stops the further reaction.
    (iii)  There are impurities in the metal.
    (iv)  The reaction becomes reversible.
