    Radioactive decay is probabilistic in nature. If you have a large number of radionuclides you can make probabilistic predictions about the group- in one half-life about half of the nuclides will have decayed. But you cannot tell when any individual will decay,

    because they dont all decay at the same time

    so you want to know why a nuclues never decays?

    because it's random when they will decay?

    Consider; i have ten coins, i flip them all over, if a tail that coin is removed, if a head the coin can be re flipped, every minute i re-flip all the coins that were heads last time, . You could do some statical analysis and predict that the game will last less then 10 minutes - most of the time. however sometimes, all coins will be tails on the first flip, and sometimes, all the coins continue to flip heads and the game never ends

    Making predictions about the coins game is similar to making predictions about the radionuclides, The data used to make the predictions is probabilistic data. [this analysis is very different to trying to determine the behaviour of a single coin, (that would require knowing trajectories, velocities and dynamics.)(we dont have this data)]

    did you try the game, do you have ten coins,? i took me exactly ten flips, but that was just lucky

    as far as i can recall, the particles in question are soo small that any attempt to measure them affects their situation.

    A radioactive nucleus is often modeled as a hollow sphere in which there is a small marble. The hollow sphere has a small hole but large enough for the marble to pass through. The marble is considered to be bouncing around in the sphere until after a time it passes through the hole and escapes. consider a piggy bank with a coin that you are trying to shake out. Is it possible to predict when the coin will come out ie. how many shakes will it take to get the coin out? I think not. You can estimate the average number shakes to get the coin out of say 10000 bank by shaking them until a coin comes out and averaging the number of shakes that released a coin. that way if you came across another set of similar bank you could estimate how long it will take to release all the coins. So goes the coin in the bank so goes the radioactive nucleus.
