Problem: Write the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by Br.

FREE Expert Solution

Recall: Elements gain or lose electrons, and in the process become ions. Ions are either positively-charged (cations) or negatively-charged (anions). The most likely formed ion of an element is the one whose electron configuration is the same as that of a noble gas (ns2np6).

Bromine belongs to Group 7A, the halogens, which tend to gain an electron. First, we need to determine the ground-state electron configuration of bromine.
