Outside a magnetic field, diamagnetic substances exhibit no magnetic properties. If there are unpaired electrons, it is paramagnetic. https://en.wikipedia.org/wiki/Paramagnetism Diamagnetic We provide you with handpicked material and question banks, time-proven exam strategies, exam analyses and simulated tests to give you a hands-on real-time test experience. He wants to investigate and end this situation as soon as possible, so he has asked the recess aides to watch closely. Paramagnetic When an atom has no unpaired electrons, it is diamagnetic. If is is C^2+ it would be 1s^2 2s^2 and e⁻s are paired: diamagnetic. There are two married couples. I believe C2 2+ is the only paramagnetic species. ? You can see that electrons in each energy levels are paired and hence diamagnetic. The filled orbitals are σ(1s)22, σ∗(1s)22, σ(2s)22, σ∗(2s)22. Since it posses 2 unpaired electrons, it is Paramagnetic in nature. So paramagnetic materials are also diamagnetic, but because paramagnetism is stronger, that is how they are classified. ?1(3e?) aa53cab65dfd85c4f59fa156f7a2cc2 species: Use MO diagram with sp blending that will improve power of ?3> ?1; s,p labels replaced to numerical labels: aa53cab65dfd85c4f59fa156f7a2cc2^+: 7e- = ?1(2e?) Prepare an adjusted trial balance on August 31? I would say B2- is paramagnetic, since when you draw the molecular bond diagram you get an unpaired electron /questions/is-b2-paramagnetic-or-diamagnetic-. ?1(4e?) B2 has two unpaired electron so it is paramagnetic whereas C2 has only paired electrons so it is diamagnetic. Removing one electron from the pi orbital still leaves one unpaired electron in the other pi* orbital. This pairs up with the electron in the highest occupied σ-orbital. you need to write the molecular orbital configuration of B2 = [ sigma (1s) ]^2 [ sigma*(1s) ]^2 [ sigma(2s) ]^2 [ sigma*(2s) ]^2 [ π(2px) ]^1 [ π(2py) ]^1. hence paramagnetic aa53cab65dfd85c4f59fa156f7a2cc2: 8e- = ?1(2e?)
