1.	Which of the following pair of elements are isotopes? *₆¹²C and ₆¹⁴C₁₇³⁵Cl and ₁₇³⁷Cl₃₅⁷⁹Br and₃₅⁸¹BrAll of the above
Answer» 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.

Answer»

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.
