Deuterium is an isotope of hydrogen. The nucleus of a deuterium atom consists of one proton and one neutron. When two deuterium nuclei fuse, helium-3 is formed, and a neutron is emitted. Give the equation that illustrates this process?

Answer:

  • [tex]^2_1H+^2_1H->^3_2He+^1_0n[/tex]

Explanation:

Remember that the atomic number of an element is the number of protons and the mass number is the number of protons plus neutrons.

1) Deuterium representation:

  • Hydrogen: ⇒ H
  • One proton: ⇒ [tex]_1H[/tex]
  • One neutron: ⇒ add 1 to the mass number = 1 + 1 = 2 ⇒ [tex]^2_1H[/tex]

2) Helium-3 representation:

  • He atom with 1 neutron: ⇒ mass number = 2 + 1 ⇒ [tex]^3_He[/tex]

3) Neutron representation

  • Atomic number 0 and mass number 1: ⇒ [tex]^1_0n[/tex]

4) Nuclear equation:

  • [tex]^2_1H+^2_1H->^3_2He+^1_0n[/tex] ← answer
