<P>PROBLEM TO BE SOLVED: To provide a variable molecular model with which various molecules can be easily assembled in accordance with a way of assembly as a result by indicating various binding states by utilizing a regular tetrahedral for a shape representing an atom. <P>SOLUTION: A variable molecular model is provided in which an atom of a non-metallic element, other than a hydrogen/rare gas element represented as a sphere, is represented as a regular tetrahedral. In accordance with a character of each atom, for single binding, a position of an apex is cut and used as a composition surface, for double binding, a portion of a side is cut and used as a composition surface and for triple binding, a surface itself is used as a composition surface. A Magic Tape(R) is then affixed to the composition surface and by using a plurality of models of atoms in such structures, various molecules can be assembled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
