Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Determine Bromine's Position in the Periodic Table
- Bromine (Br) is located in Group 17 (VIIA) of the periodic table - Group 17 elements are known as halogens
Step 3:: Identify Bromine's Electron Configuration
- Electron configuration: $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{10} 4p^{5}
- Bromine's atomic number is 35
Step 4:: Count Valence Electrons
- Bromine has $$7$$ valence electrons available for bonding
- Valence electrons are found in the outermost shell - For Group 17 elements, the number of valence electrons is 7
Final Answer
7 valence electrons are available for bonding in bromine (Br).
