its not 4.

There are two pi bonds.
H3O, Hydronium ion, has a total of three hydrogen bonds. These are single bonds from hydrogen to oxygen and form cation with +1 charge.
The atomic number of carbon is 6 It is a negative ion
a ill-ion
The oxidation number of nitrogen in the nitrate ion NO3- is 5
Oxalate ion
There are two pi bonds.
There are 5 sigma bonds along with 2 pi bonds in oxalate ion and 2 ionic bonds with potassium.
Oxalates are salts of oxalic acid containing oxalate ion. Oxalate ion is a dianion. Upon protonation, oxalate ion forms a commonly known compound, oxalic acid. The commonly known oxalate salts are sodium oxalate, potassium oxalate etc. The calcium metal ion reacts with oxalate ion to form an insoluble precipitate of calcium oxalate, which is the primary constituent of most of the common kind of Kidney stones.
When tin bonds to the oxalate polyatomic ion, it does so as tin(II), so the compound is correctly written as tin(II) oxalate, or stannous oxalate, using the old-fashioned nomenclature. Its chemical formula is SnC2O4. Tin has 2 valence electrons, and the oxalate poly needs 2 electrons, so they combine is a 1:1 ratio.
Ammonium ion has two types of bonds. 1. Co-ordianate covalant bonds between H+ and NH3 2. Covalant bonds between nitrogen and hydrogens in ammonia The total number of bonds is 4
the atoms make up carbonate ion and its charge its 4+.
Formula: (NH4)2C2O4
That compound is beryllium oxalate. Beryllium, an alkaline earth metal, has two valence electrons, which it will lose to the oxalate polyatomic ion.
Oxide is a monatomic (single-atom) ion consisting of an oxygen atom with a 2- charge (O2-). An oxide can also be just about any compound that contains oxygen in the 2- oxidation state. Oxalate is a polyatomic (multiple atom) ion consisting of 2 carbon atoms and 4 oxygen atoms, also having a total charge of 2- (C2O42-). It is derived from oxalic acid, H2C2O4.
covalent bond between carbon and oxygen in oxalate ion.
As the guava fruit ripens, the amount of oxalate ion lessens as more of it is fixed into glucose and starches. This can be seen as the fruit sweetens and becomes less tart.
