This colourful and highly popular wallchart measures 130 cm x 76 cm and covers the first 105 elements. Each group is identified by a particular tinted background and each element, photographed where possible in colour, is discussed with regard to its position in the hierarchy of matter. Additional information for each element includes chemical symbol, atomic number, atomic mass, and number of electrons. This chart is a particularly useful aid for teachers and students, and would also be an interesting and worthwhile purchase for any establishment.
