Respuesta :
D. Fluorine needs to gain only one electron to have a full octet, while nitrogen needs to gain 3.
Nitrogen retains a half-loaded p subshell that forms it better stable than fluorine.
Fluorine needs only 1 electron to perform its octet to obtain stability.
Therefore, Fluorine exists more reactive and less stable than Nitrogen.
Why is fluorine exists more chemically reactive than nitrogen?
Fluorine exists most reactive element. This exists so because N, O, and F contain 5, 6, and 7 electrons respectively in their valence shell. Therefore, fluorine needs only one electron to achieve its octet in comparison to nitrogen and oxygen, which need 2 and 3 electrons respectively.
Nitrogen has an Electronic configuration [tex]1s^{2} 2s^{2} 2p^{3}[/tex]
Fluorine has an Electronic configuration [tex]1s^{2} 2s^{2} 2p^{5}[/tex]
i.e. nitrogen contains a half-loaded p subshell that creates it better stable than fluorine.
Fluorine needs only 1 electron to achieve its octet to obtain stability.
Therefore Fluorine exists more reactive and less stable than Nitrogen.
Therefore, the correct answer is option D. Fluorine needs to gain only 1 electron to have a full octet, while nitrogen needs to gain 3.
