Ntawm qhov ntsuas kub thiab siab, hydrogen yog cov xim tsis muaj xim, tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom, tsis yog xim hlau, cov pa roj carbon diatomic nrog cov mis molecular H2. Txij li thaum hydrogen yooj yim tsim covalent compounds nrog feem ntau nonmetallic cov ntsiab lus , feem ntau ntawm hydrogen Nyob rau hauv lub ntiaj teb no muaj nyob rau hauv cov ntaub ntawv molecular xws li dej

Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog hydrogen cais raws li hauv daim ntawv teev sijhawm?

Hydrogen yog cais as ib keeb nyob rau hauv seem 'Non-Hom' uas tuaj yeem nyob hauv pawg 14, 15 thiab 16 ntawm Lub Sijhawm Sijhawm . Cov khoom uas tsis yog-hlau muaj nyob, nyob rau hauv chav tsev kub, nyob rau hauv ob ntawm peb lub xeev ntawm teeb meem: gases (Oxygen, Hydrogen & Nitrogen) thiab cov khib nyiab (Carbon, Phosphorus, Sulfur thiab Selenium).

Ib sab saum toj no, puas yog hydrogen ib qho khoom lossis cov khoom sib xyaw? Hydrogen gas (H2) yog molecule, tab sis tsis yog ib compound vim nws yog ua los ntawm ib tug xwb keeb . Dej (H2O) tuaj yeem hu ua molecule lossis a compound vim nws yog ua los ntawm hydrogen (H) thiab oxygen (O) atoms. Muaj ob lub ntsiab ntawm cov khoom sib txuas uas tuav cov atoms ua ke: covalent thiab ionic / electrovalent bonds.

Ib yam li ntawd, dab tsi yog hydrogen?

Hydrogen yog cov tshuaj lom neeg nrog lub cim H thiab atomic tooj 1. Nws muaj tus qauv atomic hnyav ntawm 1.008, txhais tau tias nws yog lub teeb tshaj plaws nyob rau hauv lub sij hawm. Hydrogen yog cov tshuaj lom neeg ntau tshaj plaws hauv ntiaj teb, nrog 75% ntawm tag nrho cov baryonic pawg hydrogen . Cov hnub qub yog tsim los ntawm feem ntau hydrogen.

Cov xim dab tsi yog hydrogen ntawm lub rooj zaum?

Hydrogen , H, yog qhov lightest keeb pom ntawm lub daim ntawv qhia hnub ntawm cov ntsiab lus. Hauv chav sov, hydrogen yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, thiab tasteless.
