Qhov Tseem Ceeb Qhov txawv - Atomic Hydrogen vs Nascent Hydrogen
Hydrogen yog cov tshuaj lom neeg. Nws yog thawj lub ntsiab lus tshuaj uas tuaj yeem pom nyob rau hauv lub sijhawm ntawm cov ntsiab lus (hauv pawg 1, lub sijhawm 1). Txhua thiab txhua yam tshuaj muaj nws tus kheej lub cim. Lub cim tshuaj ntawm hydrogen yog H. Ib qho isotope ntawm hydrogen muaj ib qho proton hauv nws cov atomic nucleus. Li no tus naj npawb atomic ntawm hydrogen yog 1. Nws yog lub teeb tshaj plaws uas tuaj yeem pom hauv ntiaj teb. Atomic hydrogen thiab nascent hydrogen yog ob lo lus siv hauv chemistry los txheeb xyuas tib lub ntsiab lus hydrogen hauv kev siv sib txawv. Qhov sib txawv tseem ceeb ntawm atomic hydrogen thiab nascent hydrogen yog tias ib qho atom ntawm hydrogen los yog hydrogen tau los ntawm kev sib cais ntawm molecular hydrogen hu ua atomic hydrogen whereas nascent hydrogen yog hais txog hydrogen uas yog liberated thaum muaj tshuaj tiv thaiv.
Atomic Hydrogen yog dab tsi?
Hydrogen tau los ntawm kev sib cais ntawm molecular hydrogen hu ua atomic hydrogen. Yog li atomic hydrogen yog cais hydrogen. Ib qho atom ntawm hydrogen muaj ib qho txiaj ntsig zoo proton nyob rau hauv lub nucleus thiab ib qho hluav taws xob tsis zoo ua khi rau lub nucleus ntawm Coulomb rog. Thaum xav txog qhov tshwm sim ntawm atomic hydrogen, kwv yees li 70-75% ntawm cov teeb meem ib txwm nyob hauv lub ntiaj teb yog atomic hydrogen.
Daim duab 1: Atomic Structure of Protium
Atomic hydrogen yog tsawg heev nyob rau hauv lub ntiaj teb crust vim nws siab reactivity thiab zog. Atomic hydrogen nyiam tsim molecular hydrogen (H2) lossis lwm cov tebchaw kom tau txais lub zog qis dua uas ruaj khov.
Atomic hydrogen tuaj yeem pom hauv peb lub isotopes loj. Isotopes yog cov atoms ntawm tib cov tshuaj uas muaj tib tus naj npawb ntawm protons tab sis txawv cov lej ntawm neutrons (lossis neutrons tsis tuaj). Muaj peb lub isotopes loj: Protium, Deuterium thiab Tritium. Protium tsis muaj neutrons hauv nws cov atomic nucleus; Deuterium muaj ib tug neutron thaum tritium muaj ob. Protium yog cov isotope tshaj plaws.
tib lub electron nyob rau hauv atomic hydrogen yog nyob hauv s orbital. Atomic hydrogen muaj peev xwm tsim tau sigma covalent bonds, tab sis tsis yog pi bonds vim tsis muaj p orbitals. Daim ntawv ionic ntawm atomic hydrogen yog hydrogen ion, uas tsis muaj nws cov electron. Nws yog cation. Cov cim tshuaj rau hydrogen ion yog H+
Npaj Atomic Hydrogen
Muaj ob txoj hauv kev kom tau txais atomic hydrogen.
Thermal Dissociation Reactions
Ntawm no, molecular hydrogen (H2) yog rhuab mus rau qhov kub siab heev txog li 500 ° C. Tom qab ntawd cov hydrogen molecules dissociate rau hauv atomic hydrogen. Txawm li cas los xij, qhov no tseem yog txoj hauv kev theoretical
Txoj Kev Tso Hluav Taws Xob
Qhov no ua tiav ntawm 0.1 - 1.00 mmHg siab hauv lub raj xa hluav taws xob. Lub kaw lus ua haujlwm siv molecular hydrogen (hydrogen gas). Tungsten electrodes yog siv los npaj lub nkoj hluav taws xob
Nascent Hydrogen yog dab tsi?
Lub sij hawm nascent hydrogen yog siv los hu hydrogen uas yog liberated thaum muaj tshuaj tiv thaiv. Nws yog suav hais tias hydrogen liberated thaum lub sij hawm kev loj hlob ntawm cov tshuaj tiv thaiv tshuaj yog pib nyob rau hauv lub atomic xeev; Tom qab ntawd nws tau muab tso ua ke los tsim cov hydrogen molecular thiab tso tawm raws li hydrogen gas (lossis lwm yam, qhov no atomic hydrogen yuav hnov mob nrog qee yam muaj ions). Piv txwv li, Zn + 2HCl → ZnCl2 + 2[H]
Dab tsi zoo sib xws ntawm Atomic Hydrogen thiab Nascent Hydrogen?
- Ob leeg yog cais atomic xeev ntawm hydrogen.
- Ob hom no muaj zog heev thiab muaj zog.
Qhov txawv ntawm Atomic Hydrogen thiab Nascent Hydrogen yog dab tsi?
Atomic Hydrogen vs Nascent Hydrogen |
|
| Atomic hydrogen hais txog hydrogen tau los ntawm kev sib cais ntawm molecular hydrogen. | Nascent hydrogen yog hais txog hydrogen uas tau tso tawm thaum muaj tshuaj lom neeg. |
| Daim ntawv thov | |
| Atomic hydrogen yog ib qho kev sib cais ntawm hydrogen, uas yog reactive thiab nquag; Nws yog ib qho tseem ceeb hauv lub qab ntuj khwb. | Nascent hydrogen yog thawj lub xeev atomic ntawm hydrogen uas tsim thaum muaj tshuaj lom neeg. |
Summary – Atomic Hydrogen vs Nascent Hydrogen
Atomic hydrogen yog daim ntawv cais ntawm cov tshuaj lom neeg, hydrogen. Nascent hydrogen kuj yog ib daim ntawv cais ntawm hydrogen. Tab sis ob lo lus no txawv ntawm lawv daim ntawv thov. Qhov sib txawv tseem ceeb ntawm atomic hydrogen thiab nascent hydrogen yog tias ib lub atom ntawm hydrogen los yog hydrogen tau los ntawm kev sib cais ntawm molecular hydrogen hu ua atomic hydrogen whereas lub sij hawm nascent hydrogen yog siv los hu hydrogen uas yog liberated thaum muaj tshuaj tiv thaiv.
