Is H2SO4 ionic compound?
Sulfuric acidSulfuric acid / IUPAC ID
Therefore, sulfuric acid is a compound with covalent, since all the bonds are covalent. But Sulphuric acid is a very strong acid, it completely ionizes into hydronium( H3O+ ) and hydrogen sulfate ions ( HSO4− ) in aqueous solution. H2SO4 is an ionic compound but it has covalent bonds.
What is the charge of CrO4?
-2
Chromate is an ion that contains one chromium atom (in its +6 oxidation state) and four oxide atoms. Its formula is CrO4. Its overall charge is -2.
What is the charge of CrO4 2 -)?
There are one chromium atom and four oxygen atoms in the chromate ion. Also, there is a -2 overall charge on the CrO42- ion which is also should be considered to draw the lewisstructure.
What is the name of the polyatomic ion ClO4 −?
Perchlorate | ClO4- – PubChem.
Why is ClO4 called perchlorate?
The anion with one more oxygen atom than the (root)ate anion is named by putting per- at the beginning of the root and -ate at the end. For example, ClO4 − is perchlorate. The anion with one fewer oxygen atom than the (root)ate anion is named with -ite on the end of the root.
What is Cr2O7?
dichromate | Cr2O7 | ChemSpider.
What is the oxidation number of Cr in cr2o72 -?
+ 6
The sum of the oxidation numbers in Cr2O72-, a polyatomic ion, is -2, the charge of the ion. There are seven oxygen atoms, so the total charge is − 2⋅7 = − 14. So, a chromium atom here has an oxidation number of + 6.

What is a polyatomic ion with a negative 3 charge?
Polyatomic ions with a minus 2 charge are also common. This is the chemical structure of the phosphate anion. Todd Helmenstine Of course, several other polyatomic ions form with the negative 3 charge, but the borate and phosphate ions are the ones to memorize.
What are the ionic compounds of polyatomic ions?
Table of Polyatomic Ions Name Formula sulfite SO 32− sulfate SO 42− hydrogen sulfate (aka: bisulfate) HSO 4− thiosulfate S 2 O 32−
What is the difference between monatomic and polyatomic ions?
We can think about polyatomic ions by comparing them to monatomic ions. A monatomic ion is an atom that has been ionized by gaining or losing electrons. The ion has a net charge because the total number of electrons is not balanced by the total number of protons in the nucleus.
What does the dot structure of a polyatomic ion represent?
For example, let’s consider the polyatomic ion , which is known as hydroxide. On the left we see the dot structure of the hydroxide ion. It contains one oxygen atom and one hydrogen atom. The single line between them represents the covalent bond, which contains two electrons shared between and . The dots around represent lone pairs of electrons.
