awesome! thanks :)

unklerhaukus · Answer

every one right except the last one

anonymous · Answer

yeahhh, i think the correct answer was O2- or something?? but i have no idea why :( can u pls explain?? :)

unklerhaukus · Answer

A  $\text O$       $1s^22s^22p^4$ not an ion 

B  $\text O^{2-}$    $1s^22s^22p^6 $

C  $\text N$        $1s^22s^22p^3 $  not an ion

D  $\text N^{3-}$   $1s^22s^22p^6 $

anonymous · Answer

okay, i seeee... but why isn't it an ion?? like how can u tell?

unklerhaukus · Answer

an ion has a charge , due to it having more or less electrons

anonymous · Answer

oh okay and so that makes the answer B yes?

unklerhaukus · Answer

yeah $\text O^{\color{red}{2-}}$

awesome! thanks :)
