This pack of metallic gray atoms are used to represent copper atoms and is for extending your existing set or for replacing lost atoms. Each pack contains 10 balls with six holes in each ball at 90 degrees. Each atom is 23 mm diameter, Why would I need these? You could use them to represent an octahedral metal atom in a complex such as [Cr(OH2)6]3+. 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.
