Register to get answer. Na + is isoelectric with Ne. In [CoF6]3–, Co is having four unpaired electrons as F– does not cause pairing of electrons in d-orbitals, whereas in case of [Co(C2O4)3]3–, C2O4 causes pairing of unpaired electrons in d–orbitals and thus there is no unpaired electron, hence it is diamagnetic in nature. and If CO gained one election, becoming CO^-, would the bond becomeweaker or stronger? Related questions. Be the first to answer this question. The diamagnetic and paramagnetic character of a substance depends on the number of odd electron present in that substance. Paramagnetic Molecules :: If the Electronic configuration of a molecule has any unpaired electrons, then that molecule is said to be Paramagnetic.
