Write the balanced nuclear equation for the beta decay of cesium-137.

₅₅Cs¹³⁷ → ₅₆Ba¹³⁷ + ⁰₋₁e

Explanation:

Beta radiations:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

Properties of beta radiations:

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation

₅₅Cs¹³⁷ → ₅₆Ba¹³⁷ + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.
