Answer

Answer:

C. [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³

Explanation:

Step1: Identify atomic number of Bi

Bismuth (Bi) has atomic number 83.

Step2: Find nearest noble - gas

The nearest noble - gas with an atomic number less than 83 is xenon (Xe) which has atomic number 54.

Step3: Determine remaining electrons

83 - 54=29 remaining electrons.

Step4: Fill orbitals for remaining electrons

The electron - filling order gives 4f¹⁴ 5d¹⁰ 6s² 6p³ for the remaining 29 electrons. So the noble - gas electron configuration of Bi is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³.
