Cov hlau reacts nrog oxygen ua form hlau oxides. Cov no hlau oxides yog qhov tseem ceeb hauv qhov xwm txheej. Magnesium oxide yaj hauv dej los tsim magnesium hydroxide tov. 2) Thaum sodium hlawv hauv huab cua, nws ua ke nrog cov oxygen ntawm huab cua los tsim sodium oxide
Yog li ntawd, ua li cas rau hlau thaum nws hnov mob nrog oxygen?
Thaum a hlau reacts nrog oxygen , a hlau oxide cov ntaub ntawv. Qhov sib npaug dav rau qhov kev tawm tsam no yog: hlau + oxygen → hlau oxide. Rust yog ib hom hlau oxide thiab nws tsim maj mam thaum hlau raug cua.
Ib tug kuj yuav nug, ua li cas hlau teb nrog oxygen dej thiab acids? Reactive heev hlau react nrog dilute kua qaub , dej , thiab oxygen . Cov ntaub ntawv pov thawj ntawm tshuaj tiv thaiv nrog ib tug dilute kua qaub yog tsim los ntawm hydrogen gas npuas. Cov no cov tshuaj tiv thaiv koom nrog kev hloov ntawm electrons los ntawm lub hlau mus rau hydrogen atoms. Tsawg reactive hlau react nrog kua qaub thiab oxygen , tab sis tsis yog dej.
Ntawm no, cov hlau thiab nonmetals ua li cas nrog oxygen?
Tsis yog - hlau reacts nrog oxygen hauv huab cua los tsim tsis yog - hlau oxides. Nov yog ob qho piv txwv rau cov tsis yog - hlau carbon thiab sulfur. Tsis yog - hlau oxides xws li sulfur dioxide thiab nitrogen oxide yog lub luag haujlwm rau cov kua qaub nag. Lawv yaj nyob rau hauv dej nyob rau hauv cov huab los tsim acidic daws.
Cov pa oxygen ua li cas nrog cov ntsiab lus?
Cov tshuaj tiv thaiv nruab nrab oxygen thiab lwm yam Feem ntau tshwm sim hauv kev tsim cov binary compound hu ua oxide. Cov tshuaj tiv thaiv nws tus kheej yog hu ua oxidation. Piv txwv li, oxidation tshuaj tiv thaiv nruab nrab oxygen thiab sodium tsim sodium oxide. Hauv ntau qhov xwm txheej, ib keeb tuaj yeem tsim ntau dua ib qho oxide.

Cov alkali hlau thiab alkaline ntiaj teb hlau sib txawv li cas?
Valance: Tag nrho cov alkali hlau muaj ib qho hluav taws xob nyob rau hauv lawv lub plhaub sab nraud thiab tag nrho cov alkaline ntiaj teb hlau muaj ob sab electrons. Txhawm rau kom ua tiav qhov kev teeb tsa tsis zoo, cov hlau alkali yuav tsum poob ib lub tshuab hluav taws xob (valence yog "ib"), thaum alkaline ntiaj teb hlau yuav tsum tshem tawm ob lub electrons (valence yog "ob")
Yuav ua li cas koj ua lub cev muaj zog nrog lub roj teeb xaim thiab cov hlau nplaum?
Cov kauj ruam Sau koj cov ntaub ntawv. Koj tsis tas yuav muaj cov cuab yeej tshwj xeeb los ua homopolar lub cev muaj zog. Muab cov hlau nplaum rau ntawm qhov ntsia hlau. Siv cov theneodymiummagnet thiab muab nws lub taub hau ntawm cov phab ntsa ntub dej. Txuas cov ntsia hlau rau ib kawg ntawm lub roj teeb. Muab cov hlau tooj liab tso rau ntawm lub roj teeb. Ua kom tiav lub cev muaj zog
Cov qauv dab tsi thaum koj nchuav hlau filings nyob ib ncig ntawm cov hlau nplaum?
Thaum cov ntaub ntawv hlau tau nchuav ib ncig ntawm cov hlau nplaum, cov duab ntawm cov hlau nplaum raug ntes. Vim li cas qhov no tshwm sim? Tsis tas li ntawd, cov ntaub ntawv hlau no cais ua cov qauv pom tseeb ntawm cov kab
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Vim li cas cov hlau ua hlau nplaum ruaj khov?
Thaum cov hlau tsis muaj hlau nplaum yog siv rau cov hlau nplaum, cov atoms nyob rau hauv nws rov kho lawv tus kheej nyob rau hauv ib yam uas tsim ib tug mus tas li hlau nplaum. Raws li cov atoms ua kom haum, lawv tsim ib qho chaw sib nqus uas tsis poob nws lub zog. Yuav kom tsim tau ib qho chaw sib nqus, ib qho khoom atoms yuav tsum tau ua kom zoo
