Answer:
yes, these are isotopes of nitrogen.
Explanation:
Any atom with the same number of protons, but a different number of neutrons is called an isotope. Nitrogen has 7 protons and 7 neutrons. If it had a different number of protons, it would be a different element. Since we know both elements A and B are Nitrogen and therefore both have 7 protons, that means they have 8 and 9 neutrons, respectively. Therefore, they are isotopes of Nitrogen.
