WebThis variation in neutron count alters the element's mass number but not its atomic number. As a consequence, although having the same physical qualities, various isotopes of the same element have distinct chemical properties. For instance, the three isotopes of carbon are carbon-12 (12C), carbon-13 (13C), and carbon-14 (14C). Web1st step. All steps. Final answer. Step 1/1. The atomic mass of an element is the weighted average of the masses of all its isotopes, taking into account their relative abundance. Therefore, we can calculate the atomic mass of antimony as follows: Atomic mass = (isotope 1 mass x abundance of isotope 1) + (isotope 2 mass x abundance of isotope 2) WebIsotopes of Elements- Isotopes refer to elements with nuclei having the same number of protons, but differing numbers of neutrons, so that the masses of contrasting isotopes … long poh seafood
