Ammonium ions
Nitrite ions can form nitrate ions by reacting with oxidizing agents such as the oxygen in air.
The spectator ions are Ag+ and (NO3)-.
Ammonium = NH4+ Nitrate = NO3-
Lead nitrate or Pb(NO3)2 , contains divalent lead ions. While Silver nitrate or AgNO3 , contains monovalent silver ions
-1
If you mean in barium nitrate, the formula is Ba(NO3)2, which is a ratio of 1Ba:2NO3.
They have mutualistic relationships with fungi and bacteria that can split atmospheric nitrogen into a form that is usable by the plants.

Calcium ions have a charge of +2 and nitrate ions (NO3) have a charge of -1. Because compounds are neutral, you need two nitrate ions to cancel out one calcium ion. Thus the formula for calcium nitrate is Ca(NO3)2. Nitrate has four atoms (one nitrogen and three oxygen). But there are two nitrate ions, so that makes eight atoms. Then you add on the one calcium atom for a total of nineatoms.
Cobalt(II) nitrate dissociates as follows:Co(NO3)2 ==> Co^2+ + 2NO3^-
they are both spectator ions.
