Chemical elements with hexagonal close-packed structure
- DysprosiumDysprosium carries a name that doubles as a confession. Paul Emile Lecoq de Boisbaudran needed more than thirty attempts to pull it free from holmium oxide…
- ZincZinc is the only metal that appears in every single enzyme class in the human body. That one fact hints at how deeply this element is woven into the fabric…
- ZirconiumZirconium sits at atomic number 40 on the periodic table, carrying a symbol - Zr - that hints at the Persian word zargun, meaning "gold-like" or "as gold."…
- CadmiumCadmium hides in plain sight. Atomic number 48 on the periodic table, it sits quietly alongside zinc and mercury in group 12, a soft silvery-white metal that…
- TerbiumTerbium, element 65 on the periodic table, lights up your living room, guides submarines through the ocean, and was discovered by accident inside a batch of…
- TitaniumTitanium is a metal that quietly surrounds us everywhere, yet most people have no idea they are touching it dozens of times a day.
- BerylliumBeryllium carries atomic number 4, making it one of the lightest solid metals on the periodic table, yet it is strong enough to be used in the mirrors of the…
- CobaltCobalt sits at atomic number 27 on the periodic table, but its story begins not in a laboratory, but in a German silver mine where frustrated miners blamed a…
- ErbiumErbium sits at atomic number 68 on the periodic table, a silvery-white metal that almost nobody encounters in its pure form.
- RutheniumRuthenium sits at atomic number 44 on the periodic table, carrying the symbol Ru. In 1844, Karl Ernst Claus, a Russian scientist of Baltic-German ancestry…
- ScandiumScandium sits at atomic number 21 on the periodic table, carrying the symbol Sc and a reputation that defies its abundance.
- YttriumYttrium sits on the periodic table with symbol Y and atomic number 39, but its story begins not in a laboratory, but in a Swedish quarry.
- GadoliniumGadolinium hides a paradox inside a hospital scanner. At body temperature, this silvery-white metal exhibits the greatest paramagnetic effect of any element.
- MagnesiumBurning magnesium reaches a temperature of roughly 3,100 degrees Celsius, and it throws off a brilliant white light rich in ultraviolet wavelengths.
- HafniumHafnium is so chemically alike its sister metal zirconium that for decades no one could prove it existed at all. Dmitri Mendeleev predicted a heavier cousin…
