Za ine Europium
Europium ndi yosadziwika kwambiri ya zinthu za dziko, mofulumira oxidizing mu mpweya. It ali ndi pansi kwambiri density pakati pa lanthanides. Its fluorescent zizindikiro amachititsa kuti ndi zofunika kwa mawonetsero ndi anti-kufalitsidwa.
Kugwiritsa ntchito & Maphunziro
Phosphorus yoyera yofiira yofiira, ma euro a ndalama zotsutsana ndi zosavomerezeka, ndi zida zowongolera za nuclear reactor.
Fun Facts
Europium imawoneka yofiira pansi pa magetsi a UV ndipo imagwiritsa ntchito ngati chida chosapanga dzimbiri pa ndalama za euro.
