Step 2:: Identify the Element
Bromine (Br) is a halogen located in Group 17 (VIIA) of the periodic table. Halogens typically form ions with a - 1 charge when they gain an electron to achieve a stable electron configuration.
Step 3:: Electron Configuration Analysis
- Bromine's atomic number is 35 - Neutral bromine has 35 electrons - In its most common ionic form, bromine gains one electron to complete its outer shell
Step 4:: Determine Ion Charge
Br^{-1}
When bromine gains one electron, it becomes a bromide ion with the following charge:
Final Answer
Key Insights: - Halogens typically form - 1 ions - The ion gains an electron to achieve a stable electron configuration - The charge is represented as Br^{- 1} in chemical notation
