Bromine was discovered in 1826 by a French chemist by the name of Antoine-Jérôme Balard. It contains a molar mass of 79.904 grams per mole (g/mol). Bromine falls within group 7 of the periodic table and is a halogen. Its atomic number is 35 and is one of seven diatomic elements. Bromine is one of two elements that holds the natural state of liquid. I chose bromine for my independent paper because of many other elements I knew little to none about, I have never heard of bromine and was interested to learn more.
The bromine name was derived from the word bromos, meaning “bad smell” or “stench”. Whilst being in group 7, Bromine contains the electron configuration: 1s22s22p63s23p63d104s24p5 or [Ar] 3d104s24p6. The physical appearance of bromine …show more content…
With this being said, bromine is used in day-to-day operations and can be found everyday products. Bromine can be obtained from the ocean (sea water), and although the sodium chloride is found more often; sodium bromide is found but in smaller quantities.
As shown in Figure 2.1 perbromate (BrO4-) is an ion. It carries a molar mass of 143.902 g/mol. Perbromate has 32 valence electrons; bromine carries 7 and oxygen carries 24 plus one since it is an ion. The Lewis structure of perbromate is a tetrahedral. Although the structure contains 32 valence electrons, it obtains a total 1 single bond and 3 double bonds. The oxygens in the Lewis structure follow the octet rule however bromine does not. Bromine (besides hydrogen) does not follow the octet due to certain exceptions.
Bromine can also found in the Earth’s crust. It is an acidic element and can be harmful and cause irritation if encountered. Bromine vapor, if exposed to, can be fatal even over a short period of time. The element reacts violently with alkali metals (Group 1) and can also be very dangerous. The most stable version of bromine is Bromine-79. Bromine-77 holds one of the longest half-lives within the periodic table when at 57
