In the bond Cl-Cl Exist Polarity I heard there is no Polarity in this bond why is that?

Thanks

Why would one of the two be positive and the other one negative?

Well that sound correct, but can I say it also about the bond F-F
Or in General I can say it about ant bond with the same Basis?
Thank you very much.

*any

ALL diatomic element molecules will be nonpolar. I would think that P4 and S8 would also be nonpolar. Carbon is nonpolar too. Ozone is polar due to its bonding and bent shape.

Oh OK thank you :)
