[quote=MarshMallows]Hmm..try +2 for the Na one and -2 for the fluorine one[/quote]
I had that from the start, it kept saying it was wrong.
I'll just ask her tomorrow, it doesn't really matter because I would get a 94 anyway
[quote=Omelet]I put in 1+ for sodium and 1- for fluorine and it is saying it's wrong.
it probably isn't she probably just made a mistake.[/quote]

[quote=MarshMallows]You're having trouble crossing charges..
Na is +1 ALWAYS
The ion Co3 is always -2
Lead (PB) has multiple oxidation states but the one in the picture is +2
Fluorine ALWAYS has a charge of -1[/quote]

edit: doesn't matter, just got locked out of the question.
you guys are right, the answer key is probably just wrong.
[quote=Omelet]The thing is, I can't put that..
If it did exist somehow, what would it's oxidation number be?[/quote]

Edit: This may help.

[quote=iNerd]First link: Sodium does not exist diatomically.
Second link: Diatomic flourine is a neutral molecule.[/quote]

He's talking about the synthesis of Na and the ion Co3 -2 which would result in Na2Co3
Alright, I should have just given you this from the start

Also, my teacher completely blows, I doubt she even took 2 chemistry courses in college.
She didn't go over this at all.
[quote=Omelet]it's not that it doesn't exist, it gave me the cation/anion and I separated it into sodium (na_2) and carbonate (co_3)
it's asking for the formula for each one, with oxidation number
sorry if i'm being confusing[/quote]
You mean, Na2Co3 - Sodium carbonate?
It disassociates into Na +1 ions and Co3 -2 ions
[quote=iNerd]I'm pretty sure two sodiums together isn't possible, and flourine's oxidation # is 0, as fluorine exists as a diatomic molecule.
EDIT: Unless the fluorine is negatively charged, then its oxidation # is -1. Otherwise, it's 0.[/quote]

all elements in pure form have a state of 0?
[quote=Fronz]Fluorine ALWAYS has an oxidation number of -1.[/quote]
Even in fluorine gas state?
[quote=TenthPole]How about you get off basilmarket and ask real people?[/quote]
First off, it's nearly midnight and I'm just starting on this because I was zonked with homework.
OT: It's two sodiums and two fluorines.
Oxidation numbers
I think sodium is 2+ and fluorine is 2-, they are not together.
