chemical composition
Substance's elemental breakdown
Chemical composition refers to the specific elements or compounds present in a substance and their proportions.
Scientists analyze chemical composition to identify materials, assess purity, or understand properties: The chemical composition of seawater includes sodium chloride and trace minerals.
The term appears in contexts from geology to food science to forensics.
