   The probability that an atom decays is constant in time.  That leads   
   directly to a declining exponential function for the number of atoms   
   which have not yet decayed.  Of course, that is exactly true only in the   
   limit of an infinite number of atoms.  If the number becomes to small,   
   then the noise in the function becomes large enough to obscure the   
   behaviour in the limit.  When you are down to one atom, it is still the   
   case that the probability that it will decay is independent of time.  So   
   you have no idea when it will decay.
