[MrCodeDude]

Write complete/correct chemical formuals (under the name) for each of the following compounds:
Mercury (I) Phosphate
I put Hg3 (PO4)2

What's the correct answer?

Hg3PO4

PO4 has a -3 charge.

 

[MrCodeDude]

Mercury (1) has a +2 charge. You have to have 3 of the Mercury (I)'s (meaning a +6 charge) with the Phosphate (which has a -3 charge), multiplied by 2 means a -6 charge?
They balance out, I think..

I'm telling ya it's Hg6

Common Ion List

Mercury I = (Hg2) +2 <-- diatomic
Phosphate = PO4 -3

Mercury I x 3 , Phosphate x 2 = (Hg2)3 (PO4)2 = Hg6 P2O8

Hmm, maybe you're correct.
