The technetium-99 nuclide radioactively decays by beta emission. write a balanced nuclear chemical equation that describes this process.

Tc-99m is a metastable isomer of Tc-99. It finds widespread applications in medical diagnostic procedures.

Tc-99 is also a radioactive element. It's half-life is 2,11,000 years. Upon radioactive decay, it emits beta particles and gets converted into stable compound Ruthenium-99

This process of radioactive decay is shown below.

99 43Tc → 99 44Ru + 0 - 1e
