Answer 2

Explanation:

(a)Hydrogen has only one electron in its valence shell,but H⁻having two electrons in its valence shell so its electronic configuration is $1s^{2}$.

(b)Sodium has only eleven electron in its valence shell,but Na⁺ having ten electrons in its valence shell so its electronic configuration is$1s^{2}2s^{2}2p^{6}$.

(c)Oxygen has only eight electron in its valence shell,but O²⁻having ten electrons in its valence shell so its electronic configuration is$1s^{2}2s^{2}2p^{6}$.

(d)Flourine has only nine electron in its valence shell,but F⁻ having ten electrons in its valence shell so its electronic configuration is$1s^{2}2s^{2}2p^{6}$.
