SATHEE: Atomic Structure Question 309

Atomic Structure Question 309

Question: The configuration $1 s^{2},, 2 s^{2} 2 p^{5},, 3 s^{1}$ shows [Pb. PMT 2002]

Options:

A) Excited state of $O_{2}^{-}$

B) Excited state of neon

C) Excited state of fluorine

D) Ground state of fluorine atom

Show Answer

Answer:

Correct Answer: B

Solution:

The ground state of neon is $1 s^{2} 2 s^{2} 2 p^{6}$ on excitation an electron from $2 p$ jumps to $3 s$ orbital. The excited neon configuration is $1 s^{2} 2 s^{2} 2 p^{5} 3 s^{1}$ .
