Element number 43, technetium, is not naturally occurring but is prepared by nuclear reactions for use in medical imaging. The starting material, ⁹⁸Mo, captures one neutron to give a new species X. X decays by electron emission to give species Y which is formed in a metastable state. Y then decays to give ⁹⁹Tc with the emission of a gamma ray. Identify X and Y and write balanced nuclear equations for their formation and decomposition.
