Apr 02, 2016· Cesium137 has an atomic number of 55, so is written as #""_55^137Cs#. It is also a #beta#emitter, which means it undergoes #beta#decay by a neutron decaying into a proton, releasing an electron.. Protons and neutrons have the same mass, so the mass number doesn't change. The atomic number increases by one, because one more proton is formed.
