What is SO4 called?
The chemical designation SO4 refers to sulfate. Sulfate is a molecule that combines one atom of sulfur with four molecules of oxygen. While sulfate occurs naturally in water, humans and animals should not consume large amounts. Sulfate occurs in sulfite ores, shales and industrial waste and enters the water table from these sources.
What is the ionic charge of SO4?
What Is the Ionic Charge of SO4? The ionic charge of SO4 is -2. Ionic, or formal, charge is not an actual charge of the chemical, but rather an estimate of electron distribution within a molecule or ion, based on a simplified model. Formal charge of any atom in a molecule or ion can be calculated from the equation FC = GN – UE – BE.

Is so4 polar or nonpolar?
The sulfate ion or SO42- is nonpolar because there is zero net dipole in the molecule. The symmetric arrangement of Oxygen atoms nullifies the dipole moments in the molecule, which makes it a nonpolar ion.
Is so4 ionic or molecular?
The formula for this compound can be written as [Na+]2[SO42-], the sulfate anion is formed by covalent bonding between sulfur and oxygen. Since there is a bond polarity to a S-O bond these are polar covalent bonds. The attraction of the Na+ cations to SO42- is ionic. 3.
Why is so4 negatively charged?
The molecular formula for sulfate is SO42-. Four bonds, two single and two double, are shared between the sulfur and oxygen atoms. The -2 you see on the sulfate ion reminds you that this molecule is charged. This negative charge comes from the oxygen atoms that surround the sulfur atom.

What is the formal charge of S in SO4?
The formal charge of sulfur in a sulfate compound is zero. This is due to its six different resonance structures.
What is the charge of a sulfate ion?
Sulphate anion has -2 charge or it can be said that net oxidation no of the ion is -2.
How many oxygen atoms share negative charges?
By considering resonance, negative charges are equally shared by the four oxygen atoms.

How many coordinate bonds does sulfur have?
As far as I understand S O X 4 X 2 − structure, sulfur makes two coordinate bonds with two oxygen atoms and two double bonds are formed with oxygen after sulfur expands it's valance shell to 6. At this point calculating formal charge of those two coordinate bonded oxygen gives total formal charge of −2 and the formal charge on S and the double bonded O is zero. Thus the minus 2 charge on S O X 4 X 2 − can be shown but initially all the atoms were neutral. While making bonds electrons were shared only.
