(D) When a radioactive element emits an electron (beta particle,$_{-1}e^0$),the atomic number $(Z)$ of the daughter element increases by $1$ unit,while the mass number $(A)$ remains unchanged.The nuclear reaction is represented as: $_Z^A X \to _{Z+1}^A Y + _{-1}e^0$.Thus,the daughter element has an atomic number one unit more than the parent element.
