Neutrons increase the binding energy of a nucleus without adding electrostatic repulsion, potentially leading to a more stable nucleus. 112Cs 3. Ans: E 15. Median response time is 34 minutes and may be longer for new subjects. Thus α-particle emission produces a daughter nucleus with a mass number A − 4 and a nuclear charge Z − 2 compared to the parent nucleus. The emission of a positron has the effect of converting a proton to a neutron, thereby decreasing the atomic number of the nucleus by 1: [21.5] Electron capture is the capture by the nucleus of an electron from the electron cloud surrounding the nucleus.
