Answer 2

Atomic number gives number of electrons and protons .

no of neutrons = mass number - atomic number

³⁵Cl₁₇ : number of electrons = 17

           number of protons = 17

           number of neutrons = 35- 17

                                             = 18

³⁷Cl₁₇ : number of electrons = 17

           number of protons = 17

           number of neutrons = 37- 17

                                             = 20
