multiple - choice question\nchoose the larger item.\nbromine atom (br)\nbromine anion (br - 1)\nrewatch
Answer
Explanation:
Step1: Understand ion - formation principle
When an atom gains an electron to form an anion, the electron - electron repulsion increases.
Step2: Analyze size change
The increased electron - electron repulsion in the bromine anion ($Br^-$) causes the electron cloud to expand compared to the bromine atom ($Br$). So, the bromine anion is larger.
Answer:
Bromine Anion (Br - 1)
