Silicon Crystal Structural Model (often called a "molecular model")
Proudly handmade in the U.S.
Painted 7/8-inch (2.2 cm) wood balls and stainless steel rods
Dimensions: 6.2 × 6.2 × 6.2 inches (16 × 16 × 16 cm)
This handmade model is an accurate representation of the diamond cubic crystal structure of silicon at a scale of 1 Å = 25 mm (1 inch). (Magnified 250 million times.)
Physical models have been used by chemists for almost two centuries for three-dimensional representation of atomic arrangements in molecules and crystals. Their use has declined in recent decades due to advancements in computer graphics, but their importance remains in providing tactile intuition, historical connection, and inspiration.
