There are two pi bonds.
its not 4.
The atomic number of carbon is 6 It is a negative ion
H3O, Hydronium ion, has a total of three hydrogen bonds. These are single bonds from hydrogen to oxygen and form cation with +1 charge.
a ill-ion
The oxidation number of nitrogen in the nitrate ion NO3- is 5
its not 4.
There are 5 sigma bonds along with 2 pi bonds in oxalate ion and 2 ionic bonds with potassium.
covalent bond between carbon and oxygen in oxalate ion.
Oxalate ion
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.
by assuming oxalate ion. Oxalate is reducing agent and consist of2 carbon and 4oxygen , Oxygen has oxidation No:-2 and in Oxalate it becomes 4*-2=-8 and carbon has oxidation No:+3 also 2 carbon present in the oxalate ion therefor equal to =+6. C2O4 -2 +3*2-2*4=-2
This formula is itself an ion with -2 charge. It has 2 carbon atoms and 4 oxygen atoms per ion. An oxalate ion has six atoms.
In the hydronium ion (H3O+), the oxidation number of carbon is +3.

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.
