Isici somhlaba esingavamile | i-gadolinium (Gd)
Ngo-1880, uG.de Marignac waseSwitzerland wahlukanisa i-"samarium" yaba izakhi ezimbili, enye yazo eyaqinisekiswa iSolit ukuthi iyisamarium kanti enye yaqinisekiswa ucwaningo lukaBois Baudelaire. Ngo-1886, u-Marignac waqamba lesi sici esisha ngokuthi i-gadolinium ngokuhlonipha usokhemisi waseDashi u-Ga-do Linium, owathi ...Funda kabanzi -
Izakhi Zomhlaba Ezingavamile | Eu
Ngo-1901, u-Eugene Antole Demarcay wathola into entsha evela ku-"samarium" futhi wayiqamba ngokuthi i-Europium. Lokhu cishe kuqanjwe ngegama elithi Europe. Iningi le-europium oxide lisetshenziselwa izimpushana ze-fluorescent. I-Eu3+ isetshenziswa njenge-activator yama-phosphors abomvu, futhi i-Eu2+ isetshenziselwa ama-phosphors aluhlaza. Okwamanje,...Funda kabanzi -

Isici somhlaba esingavamile | I-Lanthanum (La)
I-elementi 'i-lanthanum' yaqanjwa ngo-1839 lapho umSweden okuthiwa 'uMossander' ethola ezinye izakhi emhlabathini wedolobha. Uboleke igama lesiGreki elithi 'kufihliwe' ukuze aqambe lesi sici 'lanthanum'. I-Lanthanum isetshenziswa kabanzi, njengezinto zokwakha ze-piezoelectric, izinto ze-electrothermal, i-thermoelec ...Funda kabanzi -
Isici somhlaba esingavamile | I-Neodymium (Nd)
Isici somhlaba esingavamile | I-Neodymium (Nd) Ngokuzalwa kwento ye-praseodymium, i-elementi ye-neodymium nayo yavela. Ukufika kwento ye-neodymium yenze insimu yomhlaba engavamile, yadlala indima ebalulekile emkhakheni womhlaba ongavamile, futhi yalawula imakethe yomhlaba engavamile. I-Neodymium isiphenduke indawo eshisayo...Funda kabanzi -
Isici somhlaba esingavamile | i-yttrium (Y)
Ngo-1788, uKarl Arrhenius, isikhulu saseSweden esasiyimfundamakhwela esafunda amakhemikhali kanye ne-mineralogy futhi saqoqa insimbi, wathola amaminerali amnyama abukeka njengetiyela namalahle edolobhaneni laseYtterby ngaphandle kwaseStockholm Bay, eliqanjwe ngokuthi yiYtterbit ngokwegama lendawo. Ngo-1794, i-Finnish c...Funda kabanzi -
