What is the chemical's name and formula Clues It is an ionic compound containing four ions per formula unit The cation is polyatomic It is found in bread?
yes it is found in bread
Yes. This is not only possible but universal, because a polyatomic ion is defined as a group of two or more covalently bonded elements with a net electric change. The ion as a… whole forms ionic bonds with other ions of opposite charge, but the internal bonds within the polyatomic ion are always covalent.
Generally, polyatomic ions all have charges, or valency electrons which act as the charges as a whole. They are considered as a whole category of compounds in chemistry which …have a combined charge. You should look up list of polyatomic ions for Google, if you need to learn them. To write the formula, simply look at the charges, in which for example, Sodium hydroxide. (Sodium, Na, had +1 charge, an alkaline metal element. And Hydroxide, OH - had a -1 charge, and is a polyatomic ion). The charges must equal 0, so in this case, you can simply write Sodium Hydroxide by NaOH (since +1 -1 = 0). This works normally for all other ions as well. Note that properties of the element will also alter which polyatomic ion can bond to what type of element. Multiple polyatomic ions can bond to an element also, to form other types of compounds. Also note that the name of the element came before the polyatomic ion, which is another important thing to remember. =)
Salt, acid, soda. Not sugar, pepper, gelatine, alcohol.
CO3 2- Carbonate.
If the compound contains a polyatomic ion, simply name the ion.
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?
Formulas for ionic compounds with polyatomic ions are written just like normal ionic compounds would be written like. For example, lets say your ionic compound is Ammonium nit…rate. The formula for ammonium is NH 4 and the formula for nitrate is NO 3 . The chemical formula of Ammonium nitrate will therefore be NH 4 NO 3 because ammonium has a positive charge of +1 and nitrate has a charge of -1, thus becoming neutral and forms the ionic compound Ammonium nitrate. If your compound is something like Barium hydroxide, the formula would be Ba(OH) 2 because Barium(Ba) has a charge of +2 and Hydroxide(OH) has a charge of -1. In order to neutralize the charges, you need 2 hydroxides so the subscript 2 is present. The reason the subscript is outside the parenthesis is because the subscript 2 applies to both O and H in the hydroxide poly atomic ion.
NH 3 is the molecular compoundammonia. It is sometimes confused with the ammonium ionNH 4 + .
The chemical bonding within a polyatomic ion is covalent, but the polyatomic ions are bonded ionically to some other ions of the opposite electrical charge. Note that all the …ions in a compound can be polyatomic, as in ammonium acetate. The ammonium ions are positively charged and the acetate ions are negatively charged.
Ionic bonds are formed due to the transfer of electrons from one atom (metal) to another atom (nonmetal) to give oppositely charged particles called ions to attain a noble gas… arrangement.
When a molecular compound gains or loses electrons, it becomes a polyatomic ion.

Ionic compounds ammonium sulfate, has both a polyatomic cation NH 4 + and polyatomic anion, SO 4 2-
Make sure you are familiar with the most common polyatomic ions. Look at the locations of the elements on the Periodic table. Atoms in the same column as each other tend to ex…hibit similar characteristics, including the number of electrons the elements would need to gain or lose to resemble the nearest noble gas atom.
Examples include Magnesium sulfate: MgSO4 Sodium hydroxide: NaOH Ammonium nitrate: NH4NO3.
