No, because there is one unpaired electron.
yes, silicon is diamagnetic
There are so many , all the s-block elements and most of the p-block elements, some are Sodium, Calcium, Nitrogen, carbon,sulphur. diamagnetic elements ussually have 2 electons in the last shell
The Cl2 molecule is diamagnetic. All of the electrons in its molecular orbitals are paired up. Therefore, it is not a magnetic molecule.
Yes - it is a perfect diamagnet below its transition temperature
