BETTER TO UNDERSTAND ---This molecular model is very useful for both the teacher and the student. This molecular model kit will help teachers and parents to cultivate children's interest in chemistry. Let intangible chemical molecules atomic shape transform into tangible. Better to understand and kinds will find it helpful in studying molecular geometry. A great hands-on way to learn!
POWERFUL FUNCTIONS --- This model contains C, H, O, N, P, S, F, CL, BR, I and other metals and a variety of single and double bonds, long bonds, long keys. Can be put high school, university chemistry in most of the organic or inorganic molecular structure model for the study of experimental operation.
WHAT YOU GET --- Swpeet brings you this terrific 240-piece molecular model set! Each molecular model kit comes with 86 atom pieces made up of 12 different elements. Also included are 153 links: long flexible ones (good for double and triple bonds), medium-length hard links, and two types of shorter space-filling links. Easily separate atoms from the links with the included removing tool.
NON-HAZARDOUS MATERIAL --- All models of the factory are made of food grade green plastic, new plastic, atomic ball (PP plastic, music buckle cup plastic) link key (LDPE plastic) box (ABS plastic)
CONVENIENT STORAGE --- The pieces come in a slim plastic box for convenient storage. See the pictures on this listing for a full understanding of what's inside!
