WebAug 27, 2014 · An isotope of an element has 5 protons and 5 neutrons. Determine its atomic number, Z, and its mass number, A. Name the isotope. Answer: Z = 5 (because it has 5 protons), N = 5, A = Z + N = 5 + 5 = 10 Using the periodic table, we see that the element with the atomic number of 5 is boron.
