Etymology

chromium = chrom<color> + ium<chemical element suffix>

  • chrom<color>: From Greek chrôma (χρῶμα), meaning "color," referencing the vibrant compounds of chromium.
  • ium<chemical element suffix>: A Latin-derived suffix used for metallic elements (e.g., sodium, uranium).

Etymology Origin:
Discovered in 1797, chromium derives its name from its colorful compounds, which exhibit vivid hues like red, yellow, and green. The Greek root chrôma reflects this chromatic property, while -ium aligns with naming conventions for metals. The word’s logic ties its identity to its visual chemistry.
