Document Summary

Atoms and molecules can have two kinds of magnetic properties: There is at least one electron spins that is unpaired. Notice the uppermost two electrons are unpaired, which means o 2 is paramagnetic https://socratic. org/questions/by-writing-molecular-orbital-configuration-for-no-co-o2-molecules-calculate-the- Will be given if o 2 like or n 2 like, but assume. Because heteronuclear, the inputting atomic orbitals will have different energy levels. This is due to the different ionization energy. Bigger ie lower energy level for ao. Nitrogen has higher ie than c, therefore the aos for n is a bit lower than those for c. Notice the filling is very similar to the filling for n 2 , which makes sense since cn - and n 2 are isoelectronic. The only difference is carbon has a bit lower ie than n, which put it a bit higher than n on the energy diagram. All electrons are paired diamagnetic https://www. chegg. com/homework-help/diatomic-cyanide-ion-cn-nitrosonium-ion-molecular-orbital-di-chapter-5-problem-79p-solutio n-9780321813329-exc.
