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.
A chloride contain the chloride anion (Cl-) and a cation.
No carbonate has a negative charge so it is an anion.
This is known as a Nitrate, the 'ate' ending means it has Oxygen in it, the 'Nitr' represents the Nitrogen part.
An example of this type of compound is ammonium sulfate (NH4)2SO4, where the polyatomic cation is ammonium (NH4+) and the polyatomic anion is sulfate (SO4^2-). In this case, the atoms in the sulfate anion are all from the same group in the periodic table (Group 16 or the oxygen family).
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.
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!
Neither. Silica is a covalent compound, not an ion.Silicate is an anion.
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.
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.
