About This Product
Teachers place only the parts they need directly on the whiteboard, building a nucleus and adding shells and particles to show how atoms, isotopes and ions differ. Up to 4 shells can be used on each of the two nuclei. Between lessons, the magnetic pieces are kept on the metal storing board of this Atomic Model set, which can be hung by the holes in its top corners.
Frequently Asked Questions
Q1. Is the demonstration kit magnetic? Yes. All parts except the storing board are magnetic: the electron shells, the two nuclei and the subatomic particles.
Q2. How many electron shells can be used on each nucleus? The kit has 8 electron shells, and up to 4 can be used for each nucleus.
Q3. How are the parts stored? On the 550 x 550 mm metal storing board, which has a hole in each top corner for hanging.
