Lesson-specific diagram for Structure–property–quantity synthesis. It visualizes the reasoning sequence tied to $\text{atomic structure}\to\text{bonding}\to\text{molecular structure}\to\text{property}\to\text{measurable amount}$. Text alternative: Connect microscopic electronic structure to bonding, three-dimensional molecular structure, macroscopic properties, and measurable mole-scale quantities. Choose a representation that matches the chemical scale and evidence; do not infer more precision or mechanism than the data support.
