The colors of rubies and emeralds are so striking that they define shades of red and green—ruby red and emerald green. But ...

At room temperature Chromium has a bcc (body-centered-cubic) crystal structure with a basis of one Cr atom. The unit cell is illustrated. E = 248 GPa.

Both rubies and emeralds are minerals, which is a type of rock with a consistent chemical composition and a highly ordered ...

One feature of compounds made with transition metals is their intense colour. There are many examples in nature, including ...

The striking red color of rubies is due to chromium (Cr) ions, which replace a small number of aluminum ions within the crystal structure. When chromium ions are present, they alter the way the ...

Otherwise, the Chromium projects will keep to their existing governance structures. Chromium is named for the base metal that allows the application of chrome plating, and it's a good fit.
