Ib qho chaw sib nqus sab nraud ua rau cov hluav taws xob 'spins los ua kom sib npaug mus rau qhov chaw, ua rau muaj kev nyiam net. … (Qee cov ntaub ntawv paramagnetic khaws cov kev tsis sib haum xeeb txawm tias qhov xoom xoom, txhais tau tias lawv yog paramagnetic nyob rau hauv av xeev, piv txwv li thaum tsis muaj thermal motion.)
Puas yog paramagnetic hauv nws lub xeev av?
Selenium tiag tiag muaj 2 qhov tsis sib xws ntawm electrons hauv 4p-orbital, uas ua rau nws paramagnetic.
Cov ntsiab lus dab tsi hauv av?
Atom hauv av yog ib lub atom uas tag nrho lub zog ntawm electrons tsis tuaj yeem txo qis los ntawm kev xa ib lossis ntau dua electrons mus rau qhov sib txawv orbitals. Ntawd yog, hauv av-xeev atom, tag nrho cov electrons nyob rau hauv qis tshaj qhov ua tau lub zog Piv txwv li: Xav txog cov pa roj carbon atom uas nws qhov kev teeb tsa hluav taws xob yog cov hauv qab no.
Koj paub li cas yog paramagnetic lossis diamagnetic?
Cov khoom sib nqus ntawm cov khoom tuaj yeem txiav txim siab los ntawm tshuaj xyuas nws cov khoom siv hluav taws xob: Yog tias nws muaj cov khoom siv tsis sib xws, ces cov khoom yog paramagnetic thiab yog tias tag nrho cov electrons raug ua ke, cov khoom ces yog diamagnetic.
Puas yog diamagnetic muaj zog dua li paramagnetic?
Cov lus teb sib nqus no txawv heev hauv lub zog. Diamagnetism yog ib yam khoom ntawm tag nrho cov ntaub ntawv thiab tawm tsam siv magnetic teb, tab sis tsis muaj zog heev. Paramagnetism, thaum tam sim no, muaj zog dua diamagnetism thiab tsim cov hlau nplaum nyob rau hauv cov kev taw qhia ntawm daim teb thov, thiab proportional rau daim teb thov.
