Oxidation naj npawb , kuj hu Oxidation State , tag nrho tus lej ntawm electrons uas ib tug atom yog nce los yog poob nyob rau hauv thiaj li yuav tsim ib tshuaj khi nrog lwm tus atom.
Ib yam li ntawd, koj tuaj yeem nug, koj pom tus lej oxidation li cas?
Kev piav qhia:
- Tus naj npawb oxidation ntawm cov khoom dawb yog ib txwm 0.
- Tus lej oxidation ntawm monatomic ion sib npaug ntawm tus nqi ntawm ion.
- Tus naj npawb oxidation ntawm H yog +1, tab sis nws yog -1 nyob rau hauv thaum ua ke nrog tsawg electronegative ntsiab.
- Tus lej oxidation ntawm O hauv cov tebchaw feem ntau yog -2, tab sis nws yog -1 hauv peroxides.
Tsis tas li ntawd, tus lej oxidation yog dab tsi nrog piv txwv? Cov oxidation naj npawb ntawm ib qho atom yog tus nqi nws zoo li muaj thaum koj suav cov electrons raws li qee qhov kev cai. Cov oxidation naj npawb ntawm ib qho atom nyob ntawm lwm cov atoms hauv cov khoom. Rau piv txwv , KClO, the oxidation naj npawb Cl yog +1. Hauv KClO2, lub oxidation naj npawb Cl yog +3.
Ib yam li ntawd, oxidation xeev nyob rau hauv chemistry yog dab tsi?
Ib oxidation xeev yog a tus lej uas yog muab rau ib yam hauv a tshuaj ua ke. Qhov no tus lej sawv cev rau tus lej ntawm electrons uas atom tuaj yeem nce, poob, lossis sib koom thaum sib txuas nrog ib lub atom ntawm lwm lub caij.
Puas yog oxidation xeev thiab Valency tib yam?
1. Valency yog qhov siab tshaj plaws tsis muaj. ntawm electrons uas atom yuav poob los yog nce thaum oxidation tsis muaj. yog qhov tseeb tsis muaj. ntawm electrons uas lub caij poob los yog nce los tsim ib lub molecule. 2. Valency yog cov cuab yeej ntawm ib qho atom cais thaum oxidation xeev yog xam rau ib tug atom yog tam sim no nyob rau hauv ib tug molecule i.e, nyob rau hauv ib tug bonded xeev.

Dab tsi yog oxidation naj npawb ntawm carbon hauv c2h5oh?
Cov lej ntawm oxidation tooj ntawm tag nrho cov atoms nyob rau hauv ib tug nruab nrab compound yog 0. Y = -2. Yog li Oxidation naj npawb ntawm Carbon hauv C2H5OH yog -2
Tus naj npawb ntawm protons hauv tooj liab yog dab tsi?
29 Tsis tas li ntawd, muaj pes tsawg protons neutrons thiab electrons muaj tooj liab? Tooj liab muaj tus lej atomic ntawm 29 , yog li nws muaj 29 proton thiab 29 electrons. Qhov hnyav atomic (tej zaum hu ua atomic mass) ntawm ib lub atom yog kwv yees los ntawm cov lej ntawm cov protons thiab cov naj npawb ntawm cov neutrons hauv lub nucleus ntawm lub atom.
Dab tsi yog oxidation naj npawb ntawm noble gases?
Cov ntsiab lus no tau suav tias yog cov pa roj tsis zoo kom txog rau thaum xyoo 1960, vim tias lawv cov oxidation naj npawb ntawm 0 tiv thaiv cov roj noble los ntawm kev sib txuas ua ke. Tag nrho cov pa roj carbon monoxide muaj qhov siab tshaj plaws ntawm cov khoom siv hluav taws xob hauv lawv lub plhaub sab nrauv (2 rau Helium, 8 rau tag nrho lwm tus), ua rau lawv ruaj khov
Dab tsi yog quantum naj npawb hauv chemistry chav kawm 11?
Quantum tooj tej zaum yuav raug txhais raws li ib txheej ntawm 4 tus lej nrog kev pab los ntawm peb tuaj yeem tau txais cov ntaub ntawv tiav txog tag nrho cov electrons hauv atom, piv txwv li. qhov chaw, lub zog, hom Orbital nyob, qhov chaw thiab kev taw qhia ntawm lub orbital. Nws qhia txog qib tseem ceeb ntawm lub zog lossis lub plhaub uas cov electron belongs rau
Dab tsi yog oxidation naj npawb ntawm chlorine hauv perchloric acid?
Lub xeev oxidation ntawm chlorine hauv perchloric acid yog +7. Raws li perchloric acid yog ib qho nruab nrab, tag nrho cov oxidation naj npawb ntawm cov ntsiab lus nyob rau hauv nws yuav tsum sib npaug zos rau xoom. Raws li hydrogen txuas nrog cov hlau tsis xws li chlorine thiab oxygen, nws nqa +1 oxidation xeev
