Atomic model
tap a particleEvery nucleon is drawn individually — 16 protons and 16 neutrons packed into the nucleus, with 16 electrons on shells outside.
16+1
Protons
Set the element — change this and it becomes a different atom.
160
Neutrons
Change only these and you get a different isotope of the same element.
16−1
Electrons
Sit outside the nucleus and decide the chemistry, not the element.

Stability
Sulfur has no measured radioactive isotope in this lab — its nuclei are stable, so decay must be shown as an illustration.
