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.
What is an ionic compound with a polyatomic cation and anion and the atoms from the anion are all from the same group?
An example of an ionic compound with a polyatomic cation and anion, where the atoms in the anion are all from the same group, is ammonium phosphate (NH4)3PO4. Here, the cation is the ammonium ion (NH4+), a polyatomic cation, and the anion is the phosphate ion (PO4^3−), which contains phosphorus and oxygen, both belonging to Group 15 and Group 16 of the periodic table, respectively. However, the phosphate itself does not have all its atoms from the same group; for a strict interpretation, consider a compound like ammonium sulfate ((NH4)2SO4), where the sulfate ion (SO4^2−) has sulfur from Group 16 and oxygen from Group 16 as well.
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.
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.
How do you name a compound with more than two elements?
To name a compound with more than two elements, you typically start by identifying the main cation and anion. The cation is named first, followed by the anion. If the compound contains polyatomic ions (ions made up of multiple atoms), you use the names of those ions directly. Additionally, if the compound is a coordination complex, the oxidation states of the central metal may also be indicated in the name.
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.
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.
