H2 paramagnetic or diamagnetic. So, we can write its electronic configuration as (σ 1 s) 2 . Hydrogen (molecular hydrogen) is therefore diamagnetic. Dec 21, 2019 · Here, for H2 the number of unpaired electron is 0. But in option 3 in H2 there's no unpaired electron. MO electronic configuration of H 2: (σ1s2) Is H2 diamagnetic or paramagnetic? The absence of any unpaired electrons in the Molecular orbital diagram of H 2 confirms its diamagnetic nature. This property is consistent with the behavior of molecular hydrogen, making H2 a diamagnetic molecule. Jun 12, 2025 · This successfully completes the H2 Molecular orbital diagram shown below in which the σ*1s MO stays empty. . So, that is your answer as diamagnetic. We can see it has no unpaired electrons. e, they are paramagnetic. Let it be H2- ,H2+ or He2+ ; there's an unpaired electron i. H2 is diamagnetic since all electrons in the MO diagram are paired. Then we have H 2. Hope this helps! Firstly we have H 2. Feb 21, 2025 · Diamagnetic substances are characterized by their lack of permanent magnetic dipoles, leading to a repulsion when placed in a magnetic field. To determine which of the species H2, H+ 2, and H− 2 are paramagnetic, we need to analyze the number of unpaired electrons in each species. Paramagnetic species have one or more unpaired electrons, while diamagnetic species have all electrons paired. Therefore, for di-hydrogen we will have 2 electrons. We know that one atom of hydrogen has 1 electron. But in all other case there's an unpaired electron. Oct 21, 2021 · Hydrogen is not usually called paramagnetic since monoatomic hydrogen is very unstable and hydrogen atoms will combine to form H $_2$ (meaning the magnetic moments become quenched - all the spins become paired). Therefore, it is diamagnetic. osoy zlopsnc kxf fcc jmmumhl xsdjurvs njhuljsu vbfm tfghn vvme
