Coordination Chemistry and Ligand Theory

~60 min · 15 stations

Coordination Chemistry and Ligand Theory is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify central metal ions in complex chemical structures; classify common ligands by their donor atom characteristics; visualize simple octahedral and tetrahedral metal coordination shapes.
