Which from following pairs is an example of isotones?

Options

  1. A₆¹² C ; ₆¹⁴ C
  2. B₆¹² C ; ₅¹¹ ~B
  3. C₆¹⁴ C ; ₇¹⁴ ~N
  4. D₆¹³ C ; ₅¹¹ ~B

Correct answer

B. ₆¹² C ; ₅¹¹ ~B

Step-by-step solution

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