The ETC® Atom Board

The ETC® Atom Board
Article number: ELC4051

We are pleased to introduce our new re-engineered and re-tooled atom board. Our atom board is based on the Bohr model.


This is truly an eye catching design that features scalloped "energy shells" to symbolize the various energy levels that electrons occupy which are carved directly into the 1 inch thick solid wood. Re-designed our board is now constructed entirely out of solid hardwood basswood. Beautifully carved and encased in a clear semi-gloss sealant and then finished with a second coat of varnish. Once you touch the smooth finish of the board, you begin to understand the work that has gone into this re-design. No detail has been overlooked, from the front of the board all the way to the underside with the stabilization bars, that are firmly screwed into the board and offset by even more stain and sealers.

The Bohr model depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, this is similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity. Because of its simplicity, and its correct results for systems, the Bohr model is used to introduce students to quantum mechanics.

Students will be able to build the models of every known element on the periodic table and perform various "what if" scenarios. We are now featuring ourindividual beads colored in red, blue and green. Each working set of beads includes 100 beads of each color, in individual clear boxes, for a total of300 beads.

You can find information on how to implement the complete line of ETC Montessori Chemistry Curriculum by following the link here.

The Atom Board Includes:


  • Teacher instruction and presentation lessons for various concepts
  • periodic table*, and
  • a complete set of cards of all the elements so that students can build atoms and explore additional concepts.
