Ntau dua tus naj npawb ntawm cov khoom siv hluav taws xob tsis sib xws, qhov ntau nws muaj paramagnetism. Kev teeb tsa ntawm Cr3 + (3d3) Fe2 + (3d6), Cu2 + (3d9) thiab Zn2 + (3d10) yog cov ions sab nrauv orbital complex. Li no, Fe2 +muaj qhov siab tshaj plaws uas tsis muaj hluav taws xob.

Uas tawm ntawm Cu2+ fe3+ thiab Cr3+ muaj qhov siab tshaj plaws paramagnetism?

Fe²⁺ muaj tus cwj pwm siab tshaj plaws ua raws li Cr 3+ ^{thiab tsawg kawg yog rau Cu}2+^{. μ=n (n + 2) qhov twg n yog tus lej ntawm cov hluav taws xob tsis sib xws.}

Tus twg muaj qhov siab tshaj plaws paramagnetism ntawm cov ions hauv qab no?

d6, 4 unpaired electrons, highspin complex

Yuav ua li cas ion complex muaj qhov siab tshaj plaws paramagnetic nyob rau hauv cov xwm?

Yog li, [Fe(CN)6]3− muaj qhov siab tshaj plaws paramagnetic.

YPuas yog ncl4 paramagnetic los yog diamagnetic?

Cl^- yog lub teb tsis muaj zog ligand thiab nws tsis ua rau kev sib koom ua ke ntawm unpaired 3d electrons. Li no, [NiCl₄^2- yog paramagnetic.
