Question Analysis
This question evaluates the student's ability to write the shorthand notation for an element by using the noble gas core and the valence shell configuration.

Key Concept Explanation
Shorthand notation uses the symbol of a noble gas (in square brackets) to represent the filled inner electron configuration, followed by the valence shell configuration.

Step-by-step Solution
1. Identify the noble gas before bromine (atomic number 35): Argon (Ar, atomic number 18).
2. Write the shorthand notation: [Ar] + valence shell configuration.
3. Bromi...
