Question

The configuration 1s2 2s2 2p5 3s1 shows (A) Excited state of O-2 (B) Excited state of neon (C) Excited state of fluorine (D) Ground state of fluorine atom

Tardigrade Admin · Accepted Answer

The ground state of neon is 1s2 2s2 2p6 . On excitation an electron from 2p jumps to 3s orbital. The excited neon configuration is 1s22s22p53s1

Q. The configuration $1 s^{2} 2 s^{2} 2 p^{5} 3 s^{1}$ shows

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

Excited state of neon

Excited state of fluorine

Ground state of fluorine atom

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 $1 s^{2} 2 s^{2} 2 p^{5} 3 s^{1}$

Q. The configuration 1s22s22p53s1 shows

Excited state of O2−​
