Qhov sib txawv tseem ceeb ntawm atomic oxygen thiab molecular oxygen yog qhov atomic oxygen yog qhov muaj zog heev thiab tsis muaj nyob hauv cov huab cua vim nws yog qhov uas cov pa molecular oxygen tsawg dua thiab muaj nyob hauv cov huab cua zoo li nws yog. Ntxiv mus, atomic oxygen yog dawb radical muaj lub cim O (3P) thaum lub molecular oxygen yog diatomic oxygen muaj lub cim O2
Oxygen yog cov khoom siv tshuaj muaj tus lej atomic 8. Tab sis thaum peb xa mus rau oxygen hauv kev siv ntau, peb tab tom tham txog molecular oxygen uas peb ua pa. Nws muaj ob lub pa oxygen atom sib koom ua ke ntawm covalent daim ntawv cog lus. Atomic oxygen muaj ib qho oxygen atom. Yog li ntawd, nws tsis tuaj yeem nyob ua ib hom tshuaj lom neeg vim nws qhov kev ua haujlwm siab.
Atomic Oxygen yog dab tsi?
Atomic oxygen yog hom tshuaj lom neeg uas muaj cov cim O (3P). Nws yog ib qho dawb radical. Qhov no txhais tau hais tias atomic oxygen muaj ib qho hluav taws xob tsis sib xws uas ua rau lub atom no muaj zog heev. Yog li ntawd, lub atom no tsis muaj nyob rau ib lub sij hawm luv luv; nws nyiam hnov mob nrog lwm cov tshuaj los yog cov khoom sib txuas kom ruaj khov los ntawm kev sib koom ua ke nws cov hluav taws xob tsis sib xws.
Daim duab 01: Oxygen Atom
Txawm li cas los xij, hauv qhov chaw sab nrauv, kwv yees li 96% ntawm cov pa oxygen muaj nyob hauv cov pa atomic vim tias muaj UV hluav taws xob ua rau lub ntiaj teb qis qis. Hom tshuaj no ua lub luag haujlwm tseem ceeb hauv corrosion hauv qhov chaw. Corrosion nyob rau hauv qhov chaw yog corrosion ntawm cov ntaub ntawv uas tshwm sim nyob rau hauv qhov chaw.
Molecular Oxygen yog dab tsi?
Molecular oxygen yog diatomic oxygen uas muaj lub cim O2 Nws muaj ob lub pa atoms sib koom ua ke ntawm covalent bonding. Muaj ob txoj kev sib txuas ntawm ob lub atom no. Txij li thaum ob lub atoms oxygen muaj yim electrons nyob ib ncig ntawm lawv, cov pa molecule tsis tshua muaj reactive.
Daim duab 02: Tsim cov Molecular Oxygen
Yog li ntawd, hom tshuaj no muaj nyob hauv qhov chaw nws tus kheej. Peb qhov chaw muaj li 21% molecular oxygen. Cov pa oxygen no yog qhov tseem ceeb rau txhua yam kab mob rau lawv txoj kev ua pa. Nws tshwm sim raws li cov roj tsis muaj xim thiab qhov kub ntawm qhov kub yog -183 ° C.
Qhov txawv ntawm Atomic Oxygen thiab Molecular Oxygen yog dab tsi?
Atomic oxygen yog hom tshuaj lom neeg uas muaj cov cim O (3P). Nws tsis muaj nyob ib txwm nyob rau lub sijhawm luv luv, tab sis nyob rau hauv qhov chaw sab nrauv, nws yog qhov tseem ceeb ntawm cov pa oxygen. Ntxiv mus, nws yog heev reactive. Molecular oxygen yog diatomic oxygen uas muaj lub cim O 2Nws muaj nyob hauv peb cov huab cua (kwv yees li 21%). Tsis tas li ntawd, nws tsis tshua muaj tshwm sim.
Summary – Atomic Oxygen vs Molecular Oxygen
Atomic thiab molecular oxygen yog cov tshuaj lom neeg tau txais los ntawm cov khoom siv tshuaj, cov pa oxygen uas muaj tus lej atomic 8. Qhov txawv ntawm atomic oxygen thiab molecular oxygen yog qhov atomic oxygen muaj zog heev thiab tsis muaj nyob hauv cov huab cua raws li nws. yog qhov uas molecular oxygen tsawg reactive thiab muaj nyob rau hauv cov huab cua raws li nws yog.
