Will Cl 35 and Cl 37 have different valencies? Justify your answer.

No, both Cl 35 and Cl 37 will have same valencies as they are the isotopes of the same element. That is, isotopes have the same number of electrons and protons. They differ only in the number of neutrons and hence their electron distribution will be same.
