Nws muaj ob lub protons, ob lub neutrons thiab ob lub electrons. Nws atomic mass yog 4.0026 amu. Peb tuaj yeem pom los ntawm kev sib tham saum toj no tias hydrogen tsuas muaj 1 proton uas yog lub luag haujlwm rau qhov hnyav atomic. Yog li, hydrogen yog lub teeb tshaj plaws.
Dab tsi yog lub teeb ci tshaj plaws?
Hydrogen, ntau tshaj plaws hauv ntiaj teb, yog cov tshuaj lom neeg nrog atomic tooj 1, thiab atomic mass ntawm 1.00794 amu, lub teeb tshaj plaws ntawm txhua yam paub. Nws tshwm sim raws li cov pa roj carbon diatomic (H2). Hydrogen yog cov roj ntau tshaj plaws hauv lub qab ntuj khwb.
Dab tsi tsim cov ntsiab lus lightest?
Cov ntsiab lus lightest (hydrogen, helium, deuterium, lithium) tau tsim hauv Big Bang nucleosynthesis. … Qhov no ua rau muaj kev tsim cov teeb pom kev zoo: hydrogen, deuterium, helium (ob isotopes), lithium thiab kab ntawm beryllium. Nuclear fusion hauv hnub qub hloov hydrogen rau hauv helium hauv txhua lub hnub qub.
Yuav ua li cas yog vim li cas hydrogen yog lub teeb tshaj plaws?
Hydrogen yog lub teeb vim nws cov molar loj tsuas yog 2 g mol−1 thiab cov roj av ruaj khov nyob ib puag ncig tsis hais hom roj. Hydrogen yog lub teeb tshaj plaws.
Vim li cas lithium tsawg tsawg?
Pom ntau ntawm lithium
Hydrogen thiab helium feem ntau, cov seem seem nyob rau hauv lub paradigm ntawm Big Bang. Li, Be thiab B yog tsis tshua muaj vim tias lawv tsis zoo sib txuas hauv Big Bang thiab tseem nyob rau hnub qub; lub ntsiabqhov chaw ntawm cov ntsiab lus no yog cosmic ray spallation.
