This pack of black atoms are used to represent carbon atoms and is for extending your existing set or for replacing lost atoms. Each pack contains 10 balls with five holes in each ball in a trigonal bipyramidal arrangement. Each atom is 23 mm diameter, Why would I need these? You could use them to represent carbon in, say, ethene or benzene in conjunction with the Molymod pink and purple shapes representing π-bonding. The Molymod system is the original, unique, dual-scale system of high quality low-cost molecular models. These enormously popular sets are ideal for students but are also used by scientists all over the world. We also sell spare packs of atoms in different shades and with differing number of holes with 1, 2, 3, 4, 5, and 6 holes elsewhere in our shop to represent different atoms and atom types.
