Is Na2Cr2O7 ionic with a polyatomic ion?
Yes, Na2Cr2O7 is an ionic compound containing the polyatomic ion dichromate (Cr2O7)^(2-). Sodium (Na) is a monovalent cation, and dichromate is a polyatomic anion formed by chromium (Cr) and oxygen (O) atoms.
What is anion cation and polyatomic ion?
Well, a polyatomic may contain a cation in it. A cation is a positively charged ion. They are usually metals. A good way to remember is: "cats" have "paws" because they are "pawsitive". Cheesy, right? Anyways, an example of a polyatomic that contains a cation is NH4+. You know that this polyatomic has a cation by the +1 superscript. This + sign signifies a positive ion, which is called a cation!
An ionic compound containg two ions per formula unit The cation contains 24 electrons the polyatomic anion conatins 5 atoms one of which is sulfur and has a charge of 2?
The ionic compound is likely calcium sulfite (CaSO3). The cation, calcium, has 24 electrons, and the polyatomic anion contains 5 atoms with one of them being sulfur (S) which has a charge of 2-. When calcium (Ca2+) and sulfite (SO32-) ions combine in a 1:1 ratio, they form an ionic compound with the formula CaSO3.
Is sodium nitrate a monovalent anion?
Not quite. Sodium nitrate is a compound composed of two monovalent ions, sodium +1 which is a cation (that is, a positively charged ion) and nitrate -1 which is an anion (a negatively charged ion) which together form a neutral or uncharged compound.
Is CsCO3 covalent or ionic?
CsCO3 is an ionic compound because it is formed from a metal cation (Cs+) and a polyatomic anion (CO3 2-). Ionic compounds typically involve the transfer of electrons between atoms with a large difference in electronegativity.
Is po43- a polyatomic anion or cation?
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.
Is Na2Cr2O7 ionic with a polyatomic ion?
Yes, Na2Cr2O7 is an ionic compound containing the polyatomic ion dichromate (Cr2O7)^(2-). Sodium (Na) is a monovalent cation, and dichromate is a polyatomic anion formed by chromium (Cr) and oxygen (O) atoms.

Is silica a cation or an anion?
Neither. Silica is a covalent compound, not an ion.Silicate is an anion.

Can an ionic compound ever consist of a cation -cation or anion-anion bond?
Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
What is an ionic compound containing 2 ions per formula unit The cation contains 28 electrons. The atoms in the polyatomic anion are in the same group on the periodic table?
One example of an ionic compound meeting these criteria is Ca(NO3)2, where the cation is Calcium with 20 electrons and the anion is nitrate (NO3-) consisting of nitrogen and oxygen, which are in the same group on the periodic table.
Which of these is an example of a polyatomic cation?
The ammonium ion, NH4+, is the only polyatomic cation.
Is calcium propionate ionic or covalent?
Calcium is a metal, and propionate is a group of non-metal atoms, so Ca-propionate is ionic.
How does a polyatomic anion different from a monatomic anion?
A polyatomic anion is a tightly bound group of atoms that behaves as a unit and has a negative charge.A monatomic anion consists of a single atom with a negative charge.
