Phawula

I-Adadium: Isimboli yenqaku v, isinyithi se-vy ye-vb, kwiqela le-VB kwitheyibhile ye-vic, inombolo ye-Atomic 23, i-Atomic Inombolo ye-Tuic Story, i-valence ngu-5,9, +2. Inqaku lokunyibilika kuka-dadium liphezulu kakhulu, kwaye ihlala i-Niobium, iTantalelom, i-tungsten, i-molybdenum njengentsimbi ye-recractory. Kuxabiseke, kunzima kwaye ungengowobukrelekrele. Inganyangeki kwi-hydrochloric kunye ne-sulfuric acid, kwaye ixhathise igesi, ityiwa, ukuchasana kwamanzi kungcono kuneyona nto ingenazithambiso. I-Andadium yentsimbi kwi-demese State iZizinza ngakumbi kubushushu begumbi. Ayisebenzi ngomoya, amanzi okanye i-alkali kwaye inokumelana ne-dilute acids vadadium yintsimbi yesilivere. Indawo yokunyibilika yi-1890 ± 10 ℃, yenye yeentsimbi ezinqabileyo ngendawo ephezulu yokunyibilika. Inendawo yokubila engama-3380 ° dadam inzima, ingengoogneti, kodwa iqulethe inani elincinci lokungcola, ngakumbi i-nitrogen, ngakumbi i-hydrogen, inokunciphisa kakhulu iplastini yabo.
