The set includes 108 balls representing atoms, each colour-coded by element and with a number of holes corresponding to the valency of the specific atom. Designed to demonstrate the molecular structure of various elements and organic and inorganic compounds, by connecting balls using the various links. There are 38 medium gray links representing single covalent bonds, 36 long flexible gray links for double or triple bonds, and 12 medium purple links for contrast in certain cases. Also includes 6 lone pair electron lobes and 12 unhybridised p-lobes (flat, pear-shaped pieces). Chemical structures are outlined in the instruction leaflet.
