Question

Which of the following pair of elements are isotopes? *
₆¹²C and ₆¹⁴C
₁₇³⁵Cl and ₁₇³⁷Cl
₃₅⁷⁹Br and₃₅⁸¹Br
All of the above​

Answer 1

Answer:

All of the above

Explanation:

₆¹²C and ₆¹⁴C => Same atomic number, different no. of protons.

Thus, they are isotopes.

₁₇³⁵Cl and ₁₇³⁷Cl => Same atomic number, different no. of protons.

Thus, they are isotopes.

₃₅⁷⁹Br and₃₅⁸¹Br => Same atomic number, different no. of protons.

Thus, they are isotopes.

As all the above options are isotopes, the correct answer is All of the above.
