Question

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 2

• 
  `^2_1H+^2_1H->^3_2He+^1_0n`

Step-by-step 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: ⇒
  `_1H`
• One neutron: ⇒ add 1 to the mass number = 1 + 1 = 2 ⇒
  `^2_1H`

2) Helium-3 representation:

• He atom with 1 neutron: ⇒ mass number = 2 + 1 ⇒
  `^3_He`

3) Neutron representation

• Atomic number 0 and mass number 1: ⇒
  `^1_0n`

4) Nuclear equation:

• 
  `^2_1H+^2_1H->^3_2He+^1_0n` ← answer
