Answer : For a species diamagnetic needs to have no unpaired electrons and paramagnetic the species needs t have unpaired electrons.Answer 1) : Electronic configuration of carbon is Thus, electronic configuration of be , as it has given to their two electrons present in the outermost valence shell.This molecule behaves as a diamagnetic species, as there are no unpaired electrons in the orbitals.Response 2) Explanation : The electronic configuration of Lithium is When the lithium is in the state that has electronic configuration as This shows that Lithium has an electron that is available in the 2p orbital, and also is uneven. Therefore, the species behave as a substance paramagnetic.Answer 3) the Boron has electronic configuration as Well ,the excited state will be ,Here, Boron in an excited state has an unpaired electron in the 2p orbital remaining 2 electrons are paired in the 2p orbital.This will as a substance paramagnetic.
