Question

Which of the following electronic configuration represents noble gas?

• A. $n{s}^{2}n{p}^6$
• B. $n{s}^{2}n{p}^5$
• C. $n{s}^{2}n{p}^4$
• D. $n{s}^{2}n{p}^3$

Answer 1

Answer: (A)

Noble gases have fully filled valence shell electronic configuration. Therefore, it represents $n{s}^{2}n{p}^6$.
