Atomic model
tap a particleEvery nucleon is drawn individually — 106 protons and 163 neutrons packed into the nucleus, with 106 electrons on shells outside.
106+1
Protons
Set the element — change this and it becomes a different atom.
1630
Neutrons
Change only these and you get a different isotope of the same element.
106−1
Electrons
Sit outside the nucleus and decide the chemistry, not the element.

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