Chlorine solar abundance

Bromine is the 62nd most abundant element found on Earth. Although it is not found uncombined in nature, it is widely distributed over the Earth in low concentrations. It is found in seawater at a concentration of 65 ppm. This concentration is too low for the bromine to be extracted directly, so the salt water must be concentrated, along with chlorine and other salts, by solar evaporation, distillation, or both. 

Fig. 8.5. The delicious cocktail of the supernovas. Mixing 13 measures of SNll with 1 measure of SNl, we find a composition of matter that approaches observed abundances in the Solar System. Certain isotopes of chlorine, potassium and scandium, among others, are not produced in snfficient qnantities, however. (From Nomoto et at. 1997.)...
