Atomic model
tap a particleEvery nucleon is drawn individually — 28 protons and 31 neutrons packed into the nucleus, with 28 electrons on shells outside.
28+1
Protons
Set the element — change this and it becomes a different atom.
310
Neutrons
Change only these and you get a different isotope of the same element.
28−1
Electrons
Sit outside the nucleus and decide the chemistry, not the element.

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