4. The electron structure of bromine is illustrated below. In chemical reactions, how does the valence configuration of bromine tend to change? A. It gains two electrons. B. It gains one electron. C. It loses one electron. D. It loses two electrons.

Answer 1

The electron structure of Bromine reveals that it has 7 electrons in its outer shell, just like all other elements of Group 17 in the periodic table to which it belongs. Among the provided reactions, the valance configuration of Bromine tends to change in such ways that it gains 1 electron. This is because it already has 7 electrons in its valence shell, and gaining 1 more will make the total become 8 electrons - a concept in chemistry known as a "full octet."The complete filling of the valence shell allows Bromine to achieve a more stable electronic configuration as it resonates with the electronic configuration of noble gases which is the most stable. Therefore, option B. "It gains one electron" is the proper answer under the given condition.Thus, the accurate answer is: **B. Bromine tends to gain one electron in its valence shell during chemical reactions.**
