Break Down the Problem

1. Identify the atomic number of xenon (Xe).
2. Determine the electron configuration of xenon based on its atomic number.
3. Compare the provided options to find the correct noble gas configuration.

Relevant Concepts

• The atomic number of xenon is 54.
• Noble gas configuration is written by using the nearest noble gas preceding the element, followed by the electron configuration of the remaining electrons.

Analysis and Detail

1. Electron Configuration of Xenon:

   • Xenon has 54 electrons.
   • The noble gas preceding xenon is krypton (Kr), which has an electron configuration of $[Kr] = 1s^22s^22p^63s^23p^64s^23d^{10}$.
   • The total number of electrons after krypton will be $54 - 36 = 18$ electrons left to account for.
   • These additional electrons fill the 4p orbital: $4p^6$.

   Thus, the complete electron configuration of xenon can be represented as: $[Kr] 5s^24d^{10} 5p^6$

2. Analyzing Answer Choices:

   • $[Xe]$ - incorrect, as it refers to itself.
   • $[Kr] 5s^{2} 4d^{10} 5p^{6}$ is the correct answer.
   • $[Ar] 4s^{2} 3d^{10} 4p^{6}$ - incorrect, as it uses argon instead of the nearest noble gas.

Verify and Summarize

• The answer $[Kr] 5s^{2} 4d^{10} 5p^{6}$ correctly represents the noble gas configuration for xenon.

Final Answer

The noble gas configuration of xenon is: $[Kr] 5s^{2} 4d^{10} 5p^{6}$
