摘要

IMPROVEMENTS IN THE MANUFACTURE OF MOLECULAR MODELS FOR THE TEACHING OF CHEMISTRY, characterized by the fact that they affect rigid plastic spheres with special shapes produced by flat sections in them, with the construction of the molecules, resulting from the union of the atoms previously mentioned, by means of flexible nylon tubes with the possibility, in the construction of these links, that by their flexibility and size molecules can be constructed in their open and compact form; when introducing these flexible tubes into holes made in the planes of the spherical caps.
