A Mina (Radioatividade)

Synopsis: Keep track animation. The animation shows that light atoms are stable, "enduring" and that nuclear instability arises due to the "excessive" increase of particles in the atomic nucleus; the more particles have the core, more "nervous" or unstable it must seem.
The animation shows a cell and a progressive zoom at its core reveal the chromosomes present there (DNA) and can be seen in the nucleus of that atom the number of protons and neutrons, which justify the position of that element in the table.
