What is the daughter nucleus (nuclide) produced when 103mo undergoes beta decay by emitting an electron?

 When  molybdenum undergo a beta decay,  a neutron change into an proton emitting electron and an electron antineutrino , since there is loss of neutron and gain of proton,  the atomic mass does not change but the atomic number increases by one, therefore an isobar of molybdenum called technetium with atomic number 43 is formed.
