As a member, you'll also get unlimited access to over 83,000 The symbol without the symbol in the box indicates that the main decay mode is by positron emission (branching ratio 96.86 %). a positron is a particle emitted from the nucleus that has the same mass as a. Positron emission increases the number of neutrons and decreases the number of protons, making the nucleus more stable or balanced. A positron is the antimatter version of the electron, with the same mass, same spin, but opposite charge. The most useful way to use positrons is by using them to probe defects in materials (positron microscopy) and defects in the human body (positron emission tomography). {{courseNav.course.mDynamicIntFields.lessonCount}} lessons Try refreshing the page, or contact customer support. In positron emission, a proton inside the radioactive nucleus is converted into a neutron while releasing a positron; in electron capture, a proton-rich nucleus of a neutral atom absorbs an inner shell electron which then converts a proton into a neutron, emitting an electron neutrino. (a) neutron emission (b) beta emission (c) positron emission (d) alpha emission (e) fission 11. Positron Emission Another particle that a nucleus can emit during a decay is a positron (0 1 e). A radioactive element decays to bromine-81 after electron capture. The positron has an electric charge of +1 e, a spin of 1/2 (same as electron), and has the same mass as an electron. The atomic number will decrease by one while the atomic weight does not change. A Geiger-Muller tube is a _____ . A) helium nucleus B) electron C) positron D) proton E) gamma photon 2.Which of the following concerning nuclear chemistry is/are correct?
