Why do different elements have different number of isotopes?

Why is caesium-137 more stable than caesium-134?

Why do nuclei decay so fast and slow?

Is it possible that every single isotope is radioactive, and isotopes which we call stable are actually unstable but have an extremely long half-life?

Why is technetium unstable?

Why are synthetic elements unstable?
