Transformation is at the heart of nuclear fire



Every twelve minutes an unbound neutron decays into a set of charged particles.

neutron decay

The decay of neutrons due to the weak force

creates protons and neutrinos.


By definition a proton is a hydrogen ion.

If the proton captures an electron


the hydrogen atom has a positive charge countered by the electron's (blue) negative charge.

planetary model

Once, the above, planetary model of the hydrogen atom was considered accurate.
