How does sodium monohydrogen phosphate form ionic bonds?

[SOLVED] Sodium monohydrogen phosphate

In a question, I came across the compound sodium monohydrogen phosphate. It only gave the name and so I needed to work out the formula.

The real formula is Na2 H (PO4). I am wonderin about the bonding of this molecule. Phosphate has a -3 charge. H could accept or give away an electron right? And the sodiums are metals, which want to give away an electron each.

How do they bond together? How could I work out that formula knowing this?


Cheers folk, I am not an expert on chemistry! :)

There is one hydrogen bond to an oxygen of phosphate and two ionic bonds to sodium cation with two other oxygens of phosphate.

Ah yea I see it now, very simple. Thanks.
