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.
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!
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.
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.
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.
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.

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? Explain.
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.
The ammonium ion, NH4+, is the only polyatomic cation.
Calcium is a metal, and propionate is a group of non-metal atoms, so Ca-propionate is ionic.
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.
