Morphology

chromium = chrome (semi-transparent) = chrom + ium

The suffix '-ium' signals a chemical element (helpful for learners), but the relation to 'chrome' (colour/finish) does not by itself give the specific elemental properties, so meaning is only partly predictable.

Etymology

The word chromium comes from the Greek root chroma, which means 'color', because many chromium compounds make bright, strong colors. That's why the metal's name connects to the shiny finish called chrome, and why chromium is used to help stainless steel resist rust and make a shiny surface.
