ag(nh3)2 + oxidization number?

OpenStudy (aaronq):

do you know how to assign them?

OpenStudy (anonymous):

idont know what ag is

OpenStudy (aaronq):

Ag=argentum, silver in latin

OpenStudy (anonymous):

no like idk what the oxidation number to that is. is it 1+ or 2+ ?

OpenStudy (aaronq):

NH3 is treated like a polyatomic ion (considered as a unit), it's neutral, so the only charge that's contributed by Ag is the +1 on the whole compound.

OpenStudy (aaronq):

given that it's \[Ag(NH _{3})_{2}^+ and NOT Ag(NH _{3})^{2+}\]

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

but why i dont get why it is not 2+

OpenStudy (aaronq):

so it's the first one? there is 2 ammonia on it? it's only 1+ because it's only lost one electron and it's a stable oxidation state. 1+ has 10 electrons in it's d-orbitals, so its full

OpenStudy (anonymous):

wait so u know its just one + b/c of the +sign on top of two rihgt?

OpenStudy (aaronq):

yeah, you would know from the plus sign here|dw:1374382244216:dw|
