Question
Aqueous solution of which salt will not contain ions with the electronic configuration $1s^2\,2s^2\,2p^6\,3s^2\,3p^6$ ?
✓
Answer
a
$NaF$ is composed of $Na^+$ and $F^-$
$NaF$ is composed of $Na^+$ and $F^-$
$N{a^ + } \to [He]\,2{s^2}\,2{p^6}$
${F^ - } \to [He]\,2{s^2}\,2{p^6}$
Hence do not match with the configuration given in the question.
