Lanthanum, mmewere 57 nke tebụl oge.
Iji mee ka ụbọchị nke ihe dị iche iche dị mma, ndị mmadụ wepụtara ụdị ihe 15, gụnyere lanthanum, onye nke atọm dị na-abawanye na tebụl oge. Ngwongwo ha na kemịkal ha yiri. Ha na-ekerịta lattice nke atọ n'ime ahịrị nke isii nke okpokoro nke oge, nke a na-akpọkarị ya "lanthanide" ma "larre" ihe dị oke egwu ". Dị ka aha ahụ na-egosi, ọdịnaya nke Lanthanum ke ụwa jikọrọ ọnụ dị ala, nke abụọ iji centruum.
Na ngwụcha nke 1838, Swedish Chemist Descticiscanga zoro aka na Onobi ọhụrụ dị ka lanhanum. Ọ bụ ezie na ọtụtụ ndị ọkà mmụta sayensị chọpụtara na nsonaazụ ya e bipụtara n'ihi na ọ hụrụ agba dị iche iche: mgbe ụfọdụ lanthanum na-acha uhie uhie, mgbe ụfọdụ ọcha, na mgbe ụfọdụ na pink dị ka ihe nke atọ. Ihe atụ ndị a mere ka o kwenye na lanthanum nwere ike ịbụ ngwakọta dị ka ngwakọta.
Lanthanum metalbụ ọla ọcha ọcha nke enwere ike gbatịrị, jiri mma mee ka ọ sie ike na mmiri oyi, na-emeghachi omume na mmiri ọkụ, ma nwee ike ịme mmiri hydrogen. O nwere ike imeghachi omume na ọtụtụ ihe na-abụghị ọla dị ka carbon, nitrogen, boron, selenium, wdg.
Ntụ ntụ na-acha ọcha na nke na-abụghịLanthanum oxidebụ ihe niile na mmepụta mmepụta ihe. Ndị mmadụ na-eji Lanthanum kama nke sodium na calcium mee ka bentoni na-agbanwe agbanwe, makwaara dị ka mkpọchi phosphorus.

Ọ bụrụ na agwọghị ya na oge, mmiri ga-amị amị, mmiri mmiri ga-aka njọ. Mwepu nke mmiri na-aga n'ihu na iji oke nke phosphorus nwere fatịlaịza amụbaala ịta nke phosphorus na mmiri. A na-agbakwunye Benton nwere lanthanum na mmiri ma nwee ike adssorb nke ọma phosphorus dị ka ọ na-abanye na mmiri. Mgbe ọ na-abanye na ala, ọ nwekwara ike ịfefee phosphorus na ala ala mmiri, gbochie ọdịnaya nke hydhorus na-enweghị ike ijide phosphate na mmiri, yabụ igbochi uto Na mmeputakwa nke green algae, ma dozie ya nke ọma site na nke phosphorus dị iche iche dịka ọdọ mmiri, overvoiris na osimiri.

A nwekwara ike iji lanthanum mee ihe na-eme ka ngwaọrụ ọhụụ, nke mere na ndị agha nwere ike mezuo ọgụ n'abalị ka ha na-eme n'ehihie. Enwere ike iji lanthanum oxide iji mepụta seramiiki cafamic, ceizoelectics na ihe X-ray.
Mgbe ndị na-achọpụta ihe ndị ọzọ na-achọ ihe ndị ọzọ na-eme, ndị mmadụ elebara anya ike ọcha, na ihe nchekwa hydrogen bụ isi ihe na ntinye nke hydrogen. N'ihi ọdịdị ọkụ na ihe mgbawa nke hydrogen, ndị nchekwa hydrogen nwere ike ịpụta skimsy.

Ọ nwere ike ijide ụmụ irighiri mmiri hydrogen na decomposen ha n'ime atọmyọden, wee chekwaa ụydọn hydrogen na lattice lattice lap iji mepụta ọla. Mgbe hydrade men a na-ewe iwe, ha ga-emebi ma hapụ akpa, nke dị obere karịa nke cylogel, ya mere enwere ike iji ya mee ihe maka batrị nickel na ụgbọ ala ngwakọ.
