Which of the following pair of nuclides is an example of isotones?

Options

  1. A₁₇³⁵ Cl , ₁₇³⁷ Cl
  2. B₁₈⁴⁰ Ar , ₁₉⁴⁰ ~K
  3. C₆¹³ C , ₅¹¹ ~B
  4. D₆¹² C , ₅¹¹ ~B

Correct answer

D. ₆¹² C , ₅¹¹ ~B

Step-by-step solution

The atoms of different elements having same number of neutrons in their nuclei are called isotones. ₆¹² C and ₅¹¹ ~B are isotones.
