Question

a. What are the isotopic symbols of all A = 17 isobars?

b. Which of these are stable nuclei?

c. For those that are not stable, identify both the decay mode and the daughter nucleus.

Short answer

Therefore, the isotopic symbols are:

${}^{17}\mathrm{F},{}^{17}\mathrm{O}\text{and}{}^{17}\mathrm{N}$

Step-by-step solution

Given information

A = 17 isobars

Explanation (a)

a.) The A =17 isobars are: ¹⁷F, ¹⁷O and ¹⁷N

Explanation (b)

b.) The ¹⁷O is stable isotope, but rare.

Explanation (c)

c.) Daughter nucleus of ¹⁷N and ¹⁷F is ¹⁷O

¹⁷F decay by electron capture..

¹⁷N decay by decay.
