REFERENCES DEFINITION RADIOACTIVE DECAY ADIOACTIVE DECAY IS A R PROCESS BY WHICH AN UNSTABLE ATOMIC NUCLEUS LOSES ENERGY EMITTING RADIATION. DEFINITION ELECTRON CAPTURE ELECTRON CAPTURE IS A TYPE OF RADIOACTIVE DECAY WHERE THE NUCLEUS OF AN ATOM ABSORBS A K OR L SHELL ELECTRON AND CONVERTS A PROTON INTO A NEUTRON. symbol electron capture CHARGE & CHANGE IN ATOMIC MASS: ELECTRON CAPTURE IS A TYPE OF ELECTRONDECAT RADIOACTIVE CAPTURE WHEREIS ATHE TYPE OF NUCLEUS OF RADIOACTIVE DECAT AN ATOM ABSORBS A WHERE K OR LTHE SHELL NUCLEUS ELECTRON OFANDAN ATOM ABSORBS CONVERTS A PROTONA INTO K OR AL NEUTRON. SHELL ELECTRON AND CONVERTS A CHARGE:PROTON INTONU,BER THE ATOMIC A NEUTRON. DECREASES BE ONE, AS A PROTON IS CONVERTED INTO A NEUTRON. CHANGE IN ATOMIC MASS: THERE IS NO CHANGE IN ATOMIC MASS NUMBER. ELECTRON CAPTURE OCCURS WHEN AN INNER-ORBITAL ELECTRON (NEGATIVELY CHARGED) IS CAPTURED BY THE NUCLEUS (POSITIVELY CHARGED). THE RESULT IS THAT A PROTON WILL COMBINE WITH THIS ELECTRON AND A NEUTRON IS FORMED. What is an atomic number? FOLLOWING ELECTRON CAPTURE, THE ATOMIC NUMBER IS REDUCED BY ONE, THE NEUTRON NUMBER INCREASED BY ONE, AND THERE IS NO CHANGE IN MASS NUMBER. ELECTRON CAPTURE PRODUCES A DAUGHTER NUCLEUS WITH ATOMIC NUMBER LESS THAN, BUT ATOMIC MASS NUMBER THE SAME AS, THE PARENT NUCLEUS. Bell, D. J. (2021, May 5). Electron capture.
