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) 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).

WebElements have families as well, known as isotopes. Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. … WebEach isotope (more properly called a nuclide) has its own way(s) in which it is formed. There is not one set way they form. So, it is not possible to give you a general answer other than to say that the isotopes of an element form in one or more of the above ways, but each isotope of an element may or may not form in a similar way as other ... community behavioral health taxonomy codesWebIsotopes of cerium.
