Abstract:
1. A periodic representation of the chemical elements for teaching chemistry structures and principles, comprising four three-dimensional forms including: a first block-shaped three-dimensional form that includes elemental representations that correspond to the alkali metals and alkaline earth metals; a second block-shaped three-dimensional form that includes elemental representations that correspond to the transition metals; a third block-shaped three-dimensional form that includes elemental representations that correspond to the metalloids, halogens and noble gases; a fourth block-shaped three-dimensional form that includes elemental representations that correspond to the lanthanides and actinides; a substantially planar map configured to be situated beneath the four three-dimensional forms, the map including four grids configured to receive each of the four three-dimensional forms and thereby indicate a particular placement of the four forms to produce periods when the three-dimensional forms are viewed together; wherein each of the elemental representations includes information about a particular element selected from the group consisting of atomic symbol, atomic number, atomic mass, the name of the element, the natural state of the element at room temperature and atmospheric pressure and number of valence electrons.
