How to solve: Which of the following is the most paramagnetic? And of course it hasn't gained weight, just experiencing a force. Anything that is magnetic, like a bar magnet or a loop of electric current, has a magnetic moment. This MO diagram should be in your textbook, and is also in anor's answer, where #"O"_2# has two unpaired electrons in … To be paramagnetic, a substance must have at least one unpaired electron. The term itself usually refers to the magnetic dipole moment. In order to be paramagnetic, there must be at least one electron with an unpaired spin. Why is Cu+ diamagnetic while Cu2+ is paramagnetic? What about #NO^(+)#? That increases its paramagnetic properties, as there exist two unpaired electrons now instead of just one. CN- has an extra electron. Diamagnetic atoms repel magnetic fields. CHALLENGE: What does that do to the #N-O# #pi# bond? Correct the number of electrons for the charge and then see if any are unpaired. Is CO paramagnetic or diamagnetic?
