radioactive atoms

Hi all. I'm wondering if anyone has ever designed a set of patterns that mimics the behavior of atomic nuclei, some stable and some radioactive. For example:

Hydrogen - a single component (i.e., a proton) that is an oscillator
Helium - two protons that interact with each other in a regular way that is periodic
...and so on, to...
Uranium - many protons that interact with each other in a regular way that is not periodic

The crux of the problem is that once there are a sufficient number of protons, the interactions never achieve periodicity. Instead, a collision occurs eventually and the pattern self-destructs. (The atom doesn't need to decay into anything meaningful.)

The key attribute of an unstable atom is that it has a random lifetime before it decays. So I would want to be able to construct an n-proton atom according to whatever rules have been imposed, and have it either be stable or decay after some unpredictable duration.

What do you think?

Cellular automata are deterministic, so to mimic random behaviour you need to implement a pseudo-random number generator, such as the Mersenne Twister.
