β-particle is emitted from the neutron of the nucleus. Write the nuclear equation for this reaction.

When a beta (β) particle is emitted from the neutron of a nucleus, the process involves the transformation of a neutron into a proton, and a beta particle (an electron) is emitted. This type of decay is known as beta decay.

The nuclear equation for this reaction is:

n → p+β−

Where:

  • represents the neutron,
  • p represents the proton,
  • β− represents the emitted beta particle (an electron).

In this process, the neutron inside the nucleus turns into a proton, and a beta particle (electron) is released. The atomic number of the element increases by 1 (because a neutron becomes a proton), but the mass number remains the same.
