These microbes are removed by “airing”the water and by adding a chemical substance called chlorine氯to the water. This kills all the microbes in the water. After this the water can be safely used for drinking. The third stage is the distribution of the purified water to homes, hospitals,...
Chlorine has been used to disinfect water for consumption in the US since the early 1900's, leading to the virtual elimination of waterborne diseases and improved public health. It is extremely effective at killing pathogens and diseases, is inexpensive, easy to control and monitor, as well as ...
One BrCl molecule has a covalent bond where chlorine is more electronegative (electron-greedy) than bromine. This causes ashift in electron density towards chlorine, resulting in a slight negative dipole. Thus bromine obtains a slight positive dipole because it is lacking electron density. ...
Chlorine has an atomic number of 17 (Z = 17). Like all Group 17 (halogen) elements, atoms of chlorine can gain an electron to form an anion (negatively charged ion) with a charge of 1-. ... We say that that the chloride ion is isoelectronic withthe argon atom. ...

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.
