Two ions which have a simlar shape are?

Question

a. CO32- and PO33-
b. OH- and SO32-
c. PO33- and NO3-
d. SO32- and PO33-
e. CO32- and SO32-

Answer 1

I think c if you mean [NO3]3-

Answer 2

whether i'm no longer completely particular of it (sorry this is been a mutually as), i've got self assurance it has to do with the Octet Rule. under the octet rule, factors tend to lose or benefit electrons with a view to have an entire valence shell. If say, Flourine (F), which has an atomic variety of 9, has 2 e interior the 1st shell and seven electrons interior the 2d shell, it would likely benefit an further electron (making it negatively charged). on condition that factors tend to "choose" having an entire valence shell, if Flourine has an entire 8 electron interior the 2d shell, it would likely stay that way. Now this is going as nicely for different factors. Say, if yet another adverse F ion comes alongside with an entire shell, it would "choose" to stay that way quite than arising a covalent or ionic bond. **As a reminder, the 1st shell can incorporate 2 electrons, and 2d shell can incorporate as much as eight. (Btw, i might desire to be incorrect. i'm at present taking Bio so I forgot a ton of stuff from my Chem type)
