This pack of yellow atoms are used to represent sulfur (sulphur) atoms and is for extending your existing set or for replacing lost atoms. Each pack contains 10 balls with with two holes in each ball at 105 degrees. Each atom is 23 mm diameter.
Why would I need these? Typically these two-hole sulfur atoms are used to represent sulfur (sulphur) in sulfides (sulphides), thiols, and thioethers.
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.
This pack of white Molydome style atoms are used typically to represent hydrogen atoms in a compact way and is for extending your existing set or for replacing lost atoms.
This pack of 10 blue atoms are used typically to represent nitrogen atoms and is for extending your existing set or for replacing lost atoms.
