What is the most unstable radioactive element?

Each element is followed by the most stable known isotope and its half-life. Note increasing atomic number doesn’t necessarily make an atom more unstable….Radioactive Elements.

Can element 115 create zombies?

Element 115 was used to create the zombies as one of its side effects was the reanimation of dead cells. The zombies were to be used as super-soldiers by the Germans. After creating them, the Germans realized that they were uncontrollable and would lead to mankind’s destruction.

What determines whether an element is stable or unstable?

Those that lie below the line of stability contain too many protons to be stable and are called “proton rich”. In summary it is the balance of protons and neutrons in a nucleus which determines whether a nucleus will be stable or unstable.
