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 ls 1s2 2s2 2p6on excitation an electron from 2p jumps to 3s orbital. The excited neon configuration is 1s2 2s2 2p2 3s1

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

Q. The configuration 1s2,2s22p5,3s1 shows

Excited state of O2−​
