Quantum zauv tej zaum yuav raug txhais raws li ib txheej ntawm 4 tus lej nrog kev pab los ntawm qhov uas 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.
Yog li ntawd, tus lej quantum hauv chemistry yog dab tsi?
A tus lej quantum yog tus nqi uas siv thaum piav txog cov qib zog muaj rau cov atom thiab molecules. Ib qho hluav taws xob hauv ib qho atom lossis ion muaj plaub tus lej quantum los piav txog nws lub xeev thiab cov kev daws teeb meem rau Schrödinger yoj sib npaug rau hydrogen atom.
Ib tug kuj yuav nug, dab tsi yog quantum tooj thiab hom quantum tooj? Hauv atoms, muaj tag nrho ntawm plaub tus lej quantum : tus thawj xib fwb tus lej quantum (n), lub orbital angular momentum tus lej quantum (l), magnetic teb tus lej quantum (ml), thiab electron spin tus lej quantum (ms).
Raws li, quantum tooj Class 11 yog dab tsi?
Quantum Numbers . Quantum zauv yog tus lej muab rau tag nrho cov electrons nyob rau hauv ib tug atom thiab lawv piav txog tej yam ntxwv ntawm lub electron. Nws tseem ceeb heev kom nkag siab Quantum Numbers kom nkag siab txog tus qauv ntawm Atom.
Dab tsi yog 4 tus lej quantum thiab txhua tus sawv cev li cas?
Kom piav qhia meej txog ib qho hluav taws xob hauv ib qho atom, plaub tus lej quantum Qhov xav tau: lub zog (n), angular momentum (ℓ), magnetic moment (mℓ), thiab spin (ms). Thawj tus lej quantum piav qhia txog lub plhaub hluav taws xob, lossis qib zog, ntawm lub atom.
