Puas H2 hu ua hydrogen lossis dihydrogen?
Vim tias muaj ob lub atom hydrogen, peb hu qhov no diatomic hydrogen, di txhais tau tias ob. Vim hais tias cov hydrogen atoms yog covalently bonded ua ke lawv tsim ib tug molecule; yog li H2 kuj tseem hu ua molecular hydrogen. Peb tuaj yeem xa mus rau nws li dihydrogen.
Vim li cas hydrogen hu ua dihydrogen?
Hydrogen muaj cov qauv atomic yooj yim tshaj plaws ntawm txhua yam nyob ib puag ncig peb hauv Xwm. Nyob rau hauv daim ntawv atomic nws tsuas muaj ib tug proton thiab ib tug electron. Txawm li cas los xij, hauv cov ntsiab lus nws tshwm sim raws li diatomic (H2) moleculethiab hu ua dihydrogen. Nws tsim cov ntsiab lus ntau dua li lwm cov khoom.
Puas yog dihydrogen yog hydrogen daim ntawv cog lus?
Nyob hauv chemistry, daim ntawv cog lus dihydrogen yog ib hom hydrogen daim ntawv cog lus, kev sib cuam tshuam ntawm cov hlau hydride daim ntawv cog lus thiab OH lossis NH pawg lossis lwm tus neeg pub dawb. Nrog lub vojvoog van der Waals ntawm 1.2 Å, hydrogen atoms feem ntau tsis mus ze rau lwm cov hydrogen atoms ze dua 2.4 Å.
lwm lub npe ntawm hydrogen yog dab tsi?
Lwm lub npe ntawm hydrogen yog protium, deuterium thiab tritium. Hydrogen's isotopes yog 1, 2, thiab 3, qhov ntau tshaj yog qhov loj 1 isotope feem ntau hu ua hydrogen (cim H, los yog 1H) tab sis kuj hu ua protium.
