Step 1:
I'll solve this Lewis dot diagram problem following the specified formatting guidelines:

Step 2:
: Determine the number of valence electrons for Bromine

• Bromine has $$7$$ valence electrons
• Bromine is in Group 17 (VIIA) of the periodic table

Step 3:
: Sketch the basic Lewis dot diagram structure

• Follow the octet rule (aim for $$8$$ electrons total)
• Place the Br symbol in the center of the diagram

Step 4:
: Distribute electrons

• Place single electrons on each side of the Br symbol first • Pair up remaining electrons to create lone electron pairs

Step 5:
: Draw the final Lewis dot diagram

- $$1$$ single electron on each of the four sides
• The diagram will have: - Br symbol in the center

Final Answer

\begin{array}{c} \cdot \ \cdot \mathrm{Br} \cdot \ \cdot \end{array} This Lewis dot diagram represents a neutral bromine atom with its 7 valence electrons distributed around the symbol.
