The Periodic Table of elements is a tool that brings some order to a vast amount of chemical information. An elements location in the table is an excellent guide to its properties and the kinds of compound it forms. To date, the Periodic Table already includes 112 elements. At the back of this Periodic Table are useful. SI units and conversion factors and the strength of commercially available concentrated acids and bases, which chemistry teachers and students will find useful.

Now available in school bag size for students and in poster size for laboratory or classroom display. The table carries 112 elements including Unq, Unp, Unh and the iupac atomic weight data. The boiling point, melting point and electro-negativity value of each element are given.

LABORATORY SAFETY 1993 P 50.00

Accidents in the laboratory may be caused by ignorance or carelessness. The teacher as well as the students must always be aware of the dangers of accidents so that the safety of everybody in the laboratory may be ensured.

These 6 posters focuses on the naturally occurring nutrient cycles in the environment. The chemistry concepts are presented and explained. These cycles involve the different elements: oxygen, carbon, sulfur, nitrogen, phosphorus and water. They involve the cycling of these elements in different chemical forms from the atmosphere to living organisms and back into the atmosphere.
