Hydrogen yog cov khoom siv tshuaj nrog lub cim H thiab tus lej atomic 1. Hydrogen yog lub teeb tshaj plaws. Ntawm cov txheej txheem hydrogen yog cov pa roj ntawm diatomic molecules muaj cov qauv H₂. Nws yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab kub kub heev.
Lub ntsiab hydrogen nrhiav tau nyob qhov twg?
Hydrogen discovery
Robert Boyle tsim hydrogen gas hauv 1671 thaum nws tab tom sim nrog hlau thiab acids, tab sis nws tsis yog txog 1766 uas Henry Cavendish lees paub nws. raws li qhov sib txawv, raws li Jefferson Lab. Lub ntsiab yog hu ua hydrogen los ntawm Fabkis chemist Antoine Lavoisier.
Qhov twg thiab ua li cas hydrogen nrhiav tau?
Nws nrhiav tau li cas? Tus kws tshawb fawb Askiv Henry Cavendish tau tshawb pom hydrogen ua ib qho khoom hauv xyoo 1766. Cavendish tau khiav ib qho kev sim siv zinc thiab hydrochloric acid. Nws nrhiav tau hydrogen thiab pom tias nws tsim dej thaum nws hlawv.
Thaum twg hydrogen nrhiav pom tseeb?
Hydrogen tau tshawb pom los ntawm Askiv tus kws kho mob Henry Cavendish hauv 1766. Cov kws tshawb fawb tau tsim cov hydrogen rau xyoo ua ntej nws tau lees paub tias yog ib qho khoom. Cov ntaub ntawv sau tseg qhia tias Robert Boyle tau tsim cov roj hydrogen thaum ntxov li xyoo 1671 thaum sim nrog cov hlau thiab cov kua qaub.
Leej twg pom hydrogen thawj zaug?
Tshawb nrhiav thiab siv. Xyoo 1671, Robert Boyle tau tshawb pom thiab piav qhia txog cov tshuaj tiv thaiv ntawm cov ntaub ntawv hlau thiab diluteacids, uas ua rau tsim cov roj hydrogen. Xyoo 1766, Henry Cavendish yog thawj tus paub txog cov roj hydrogen ua cov khoom siv sib cais, los ntawm kev muab cov roj los ntawm cov tshuaj tiv thaiv hlau-acid "inflammable air".
