WebMay 23, 2024 · Two naturally occurring isotopes of gallium are known: gallium-69 and gallium-71. Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. WebFrom the periodic table of elements, we will know that the atomic number of Gallium (Ga) is 31 atomic number (Z) of Ga = 31 From the atomic number of Ga, we should be able to know that Ga has 31 protons. Hence, the second step is to calculate the mass number of Gallium for each isotope given. For the Gallium isotope with 37 neutrons:
