发明名称 Teaching board apparatus
摘要 A board apparatus is arranged for educational presentation of inter-relationship relative to atomic particles and their associated energy levels relative to interaction of such particles, wherein the board structure includes a central ferrous metallic base plate formed with a perimeter framework accommodating a plurality of ferrous metallic discs to simulate atomic particles such as electrons and their interaction relative to one another. A modification of the invention includes a dispenser housing mounted to a first side of the framework and a container housing mounted to a second side of the framework to provide for the respective dispensing of the discs and the storage of writing instruments. An alignment board is reciprocatably mounted relative to a forward surface of the base plate for the positioning and alignment illustration in the use of the particles, wherein the board is arranged in a spaced relationship relative to the base plate to permit the discs to be received between the base plate and the alignment board.
