Black Molecular Model Atom, 2.2cm, 3 Holes, 10-Pack

This pack of 10 black molecular model atoms is designed as spare or replacement parts for molecular model kits. Each atom measures 2.2 cm (0.9 inches) in diameter and features 3 connection holes, each approximately 0.5 cm (0.2 inches) in diameter. Black atoms in molecular model sets typically represent carbon. These spare parts ensure that molecular model kits can be maintained and expanded as needed for chemistry instruction.
