19F) and the Cl chlorine possesses two isotopes (i.e. 35Cl and 37Cl). Some isotopes are unstable forms of elements; they are radioactive and are called radioisotopes: for example, 14C is a radioisotope of carbon. For any element, there is one isotope that is the most abundant in ...

Average atomic mass, given in atomic mass units (amu), is always similar to mass number, but it is not a whole number. Average Atomic Mass: Example Chlorine-35 has an atomic mass of 34.969 amu and accounts for 75.77% of chlorine on Earth. ...

解析 We don't round it to a whole number because we want the number of the relative atomic mass of cholorine to be as precise as possible.We really care about the significant figures,so it's better if we get more digits. 结果一 题目 why is this the relative atomic mass of chlorine ...
