Chemical elements with body-centered cubic structure
- EuropiumIn the year 1896, French chemist Eugène-Anatole Demarçay examined spectral lines from samarium-gadolinium concentrates. He noticed faint lines that did not…
- ChromiumOn the 26th of July 1761, Johann Gottlob Lehmann found an orange-red mineral in the Beryozovskoye mines in the Ural Mountains.
- MolybdenumThe name molybdenum comes from the Ancient Greek word meaning lead. For centuries, miners confused molybdenite with graphite and galena.
- PotassiumIn 1807, Humphry Davy isolated a new metal from potash using a newly invented voltaic pile. He derived the element by electrolysis of molten caustic potash.
- NiobiumIn 1801, English chemist Charles Hatchett examined a mineral sample sent from Connecticut to England. He identified a new element within the ore and named it…
- ManganeseManganese carries the atomic number 25 and exists as a hard, brittle, silvery metal. Its most common form is the stable isotope known as 55Mn.
- BariumAlchemists in the early Middle Ages found smooth pebble-like stones of mineral baryte near Bologna, Italy. These stones were called Bologna stones because…
- VanadiumIn 1801, a Spanish-Mexican mineralogist named Andrés Manuel del Río extracted compounds from a sample of Mexican brown lead ore.
- IronIron sits in the periodic table as element 26, symbol Fe, a metal of the first transition series and group 8. By mass it is the most common element on the…
- TantalumIn 1802, Swedish chemist Anders Ekeberg examined two mineral samples from Sweden and Finland. He identified a new element within these rocks that defied the…
