We have to identify the type of radioactive decay that is represented by the given equations and determine the missing product in each.

The spontaneous breakdown of a larger atomic nucleus to produce energy and smaller nucleus/nuclei is called radioactive decay.


Different types of radioactive decay are:


α-decay: The decaying nucleus produces a smaller nucleus and a helium nucleus (α-particle).


null


β-decay: 𝛽-decay can be of two types.


𝛽- decay: It is also known as negatron emission. In this type of decay a neutron is converted into a proton while an electron is ejected from the nucleus.

  • Mass number remains unchanged in this process.
  • Atomic number increases by 1.


null


𝛽+ decay: It is also known as positron emission. In this type of decay a proton is converted into a neutron while a positron is ejected from the nucleus.

  • Mass number remains unchanged in this process.
  • Atomic number decreases by 1.


null


γ-decay: This only emits γ-rays which are high-energy electromagnetic radiation. The atomic number and mass number of the decaying nucleus remain unchanged.
