C. Is it likely to be stable? Diamagnetic Molecules :: If the Electronic configuration of a molecule has only paired or spin paired electrons, then that molecule is said to be Diamagnetic. When we go back over to "N"_2, since "N" has one less electron than "O" in its atomic orbitals, "N"_2 has two less electrons than "O"_2 in its molecular orbitals. It is an exceptional case. Draw molecular orbital diagrams for O2-, O22-, and O2.

Secondly, is be2 − paramagnetic or diamagnetic? On the other hand, if there are unpaired electrons in the molecule, the substance is paramagnetic (attracted by the magnetic field). Top. Removing one electron from the pi orbital still leaves one unpaired electron in the other pi* orbital. Is Li2− Paramagnetic Or Diamagnetic? Be _valence shell configuration is 1s2 2s2. Dr Bob Although helium atoms do not combine to form He2 molecules. Since it posses 2 unpaired electrons, it is Paramagnetic in nature. Among the following, the species with one unpaired electron are: This question has multiple correct options I'm assuming you're familiar with the Molecular Orbital Theory. 1. The electron would be removed from the pi orbital, as this is the highest in energy. Which of the following molecule does not exist due to its zero bond order? Its molecular orbitals are constructed from the valence-shell orbitals of each hydrogen atom, which are the 1s orbitals of the atoms. Paramagnetic materials those with unpaired electrons are attracted by magnetic fields whereas diamagnetic materials those with no unpaired electrons are weakly repelled by such fields. Two superpositions of these two orbitals can be formed, one by summing the orbitals and the other by taking their difference. Q1: Arrange the species O 2, O 2-, O 2 + the decreasing order of bond order … The filled orbitals are σ (1s) 2 2, σ ∗ (1s) 2 2, σ (2s) 2 2, σ ∗ (2s) 2 2. 4 0.
