To find the number of neutrons in the isotopes of chlorine with atomic masses 35 and 37, we can follow these steps:1. Identify the Atomic Number of Chlorine: - The atomic number of chlorine (Cl) is 17. This means that chlor
The contribution of atomic chlorine to the chemistry of marine regions as well as the Arctic at ground level at polar sunrise is the subject of a number of recent studies. However, identifying the specific chlorine atom precursors has proven difficult. One potential approach is the measurement ...
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 ...
