Among ⁷⁹₃₅Br and ⁷⁸₃₅Br, ⁷⁹₃₅Br is more stable.
Briefly explained
We can identify which isotope in the pair is more stable. Let's review the criteria that are used to determine a stable isotope. A stable isotope will have more neutrons than protons with a neutron to proton ratio somewhere between one and 1.52 On the high atomic number, we're up to 152 at low atomic numbers were closer to one.
More stable isotopes have an even number of protons and neutrons. And stable isotopes have their proton or neutron number equal to one of these magic numbers.
⁷⁹₃₅Br has an equal to 44 N is equal to 35 With a neutron to proton ratio of 1-6 Br. Meaning 78 has 43 neutrons and 35 protons with a neutron to proton ratio of 1.23. So the neutron to proton ratios are pretty similar. We do see that we have both of these as being odd because both of these are odd.
⁷⁸₃₅Br is likely less stable. So ⁷⁹₃₅Br would be the more stable one.
