Solution

In isotopes of ₁₇Cl³⁵ and ₁₇Cl³⁷ the atomic numbers are the same; hence, their electronic configuration remains the same, and so are their chemical properties. These differ only in physical contents and weights because different number of neutrons contribute to the mass numbers of atoms which is 35 and 37.
