Furthermore, both surfaces can be used to make atoms and isotopes on, as the electron shells are marked, and everything can be stored together in one place, namely inside Bright Atom. You can, for example, let two atoms collide and move the valence electron manually so that the collision appears visual to the student.
The Bright Atom student set contains:
2 surfaces to make atoms on (which are also meant to store the electrons in).
30 protons,
30 neutrons,
30 electrons.
