Why is [Ni(NH 3) 6]Cl 2 paramagnetic but [Co(NH 3) 6]Cl 3 is diamagnetic ? Diamagnetism occurs when orbital electron motion forms tiny current loops, which produce magnetic fields. No unpaired electrons are present in this case. CO is a strong field ligand, which causes pairing of unpaired 3d electrons. Is CO paramagnetic or diamagnetic? Paramagnetic Molecules :: If the Electronic configuration of a molecule has any unpaired electrons, then that molecule is said to be Paramagnetic. Look at the elements position in the periodic table and find the electron configuration for the neutral atom. As all the electrons are now paired, CN-is diamagnetic (it is weakly repelled by a magnetic field). i put diamagnetic because thereare no lone paris is that corrects? One of the major breakthroughs of molecular orbital theory was to prove that #"O"_2# was paramagnetic. CN- has an extra electron. It's like our paramagnetic sample has gained weight. What about #NO^(+)#? A paramagnetic electron is an unpaired electron. Asked by Wiki User. By signing up, you'll get thousands of step-by-step solutions to your homework questions. CO is Diamagnetic. S2- has paired electrons in the 1s, 2s, all 3 2p, 3s, and all 3 3p orbitals. An atom is considered paramagnetic if even one orbital has a net spin. And so this balance allows us to figure out if something is paramagnetic or not. Is $\ce{[Co(NH3)4Cl2]Cl}$ a high spin complex or a low spin complex? When an external magnetic field is applied, the current loops align and oppose the magnetic field. d) Ni(CO) 4 is diamagnetic; [Ni(CN) 4] 2-and NiCl 4 2-are paramagnetic.

How do electron configurations in the same group … Some compounds and most chemical elements are paramagnetic under certain circumstances. Correct the number of electrons for the charge and then see if any are unpaired. This makes it paramagnetic (it is attracted into a magnetic field). Electron paramagnetic resonance (EPR), also called electron-spin resonance (ESR), selective absorption of weak radio-frequency electromagnetic radiation (in the microwave region) by unpaired electrons in the atomic structure of certain materials that simultaneously are subjected to a constant, strong magnetic field.The unpaired electrons, because of their spin, behave like tiny magnets. 0 unpaired electrons. If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. i belive that the bond would becomeweaker since there is one lone pari and it makes it an ion andwants to lose the added election, is that correct?
