Vanadium: Letšoao la element V, tšepe ea silevera e bohlooho, ke ea sehlopha sa VB tafoleng ea nakoana, nomoro ea atomic 23, boima ba atomic 50.9414, kristale e bohareng ba 'mele, valence e tloaelehileng ke +5, +4, +3, +2. Ntho e qhibilihang ea Vanadium e phahame haholo, 'me hangata e na le niobium, tantalum, tungsten, molybdenum e le tšepe e refractory. E bonolo, E thata ebile ha e na makenete. E hanyetsana le hydrochloric le sulfuric acid, 'me e hanyetsana le khase, letsoai, Ho hanyetsa metsi ho molemo ho feta litšepe tse ngata tse sa hloekang. Vanadium tšepe e teteaneng e tsitsitse haholoanyane mochesong oa kamore. Ha e sebelisane le moea, metsi kapa alkali mme e ka hanela acid e hlapollang Vanadium ke tšepe e bohlooho ba silevera. Sebaka se qhibilihang ke 1890±10℃, e leng e' ngoe ea litšepe tse sa tloaelehang tse nang le ntlha e phahameng ea ho qhibiliha. E na le ntlha e belang ea 3380 ° C, vanadium e hloekileng e thata, ha e na makenete, e bonolo, empa haeba e na le litšila tse nyenyane, haholo-holo naetrojene, oksijene le hydrogen, li ka fokotsa polasetiki ea tsona haholo.
