When an unstable Co nucleus undergoes beta decay, the nucleus formed is that of

Question

Quizplus · Accepted Answer

In beta decay, a neutron in an unstable nucleus is transformed into a proton, and a beta particle (electron) is emitted. This process increases the atomic number by one while keeping the mass number constant. Since cobalt (Co) has an atomic number of 27, the nucleus formed after beta decay will have an atomic number of 28, which corresponds to nickel (Ni).
