How are nitrogen atoms 14 / 7N and 15 / 7N different from each other?

Atoms that have the same structural but different quantitative composition are called isotopes.
14 / 7N tells us that the element has 7 protons and 7 neutrons (14-7 = 7)
15 / 7N tells us that the element has 7 protons and 8 neutrons (15-7 = 8)
