How can a map enhance your understanding? C2 2+ has the same number of electrons as B2, and since B2 is paramagnetic, so is C2 2+. For the prediction of number of unpaired electrons (n) of molecules or ions having total number of electrons 20: In this case, the number of unpaired electrons n = [ (20 - total electrons) ], The \(Ne_2\) diatomic molecules has 20 electrons, the total number of electrons will be 20. C2 2+ has the same number of electrons as B2, and since B2 is paramagnetic, so is C2 2+. Because the four chemical bonds between silicon and chlorine are uniformly distributed, SiCl4 is non-polar.
