1.I would say the last one because unlike beta and alpha rays they will have no effect on the mass or atomic number because they are just composed of high energy radiation
3.When a <span>radioactive nucleus</span> emits an alpha particle or
<span>a <span><span>beta </span>particle</span>, the protons, and neutrons in the new nucleus may not be in their most stable arrangement. The <span>protons </span>and neutrons can rearrange themselves to become <span>more </span><span>stable </span>and in this process, energy is emitted in the form of gamma rays.</span>
An electrolytic cell runs in the opposite direction of a galvanic cell. Applying a current to the galvanic cell Zn | Zn²⁺ || Ni²⁺ | Ni would convert the Zn anode to a cathode and cause Zn²⁺ to be reduced.
