See also categories: Scandium compounds and Scandium mineralsThe chemistry is almost completely dominated by the trivalent ion, Sc3+. The radii of M3+ ions in the table below indicate that in terms of chemical properties, scandium ions are more similar to those of yttrium than to those of aluminium. In part for this similarity, scandium is often classified as a lanthanide-like element.

Famous quotes containing the word compounds:
“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So thats the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
