What correctly provides the names and formulas of polyatomic ions?
Polyatomic ions are groups of atoms that carry a charge. Examples include the sulfate ion (SO4^2-) and the nitrate ion (NO3^-). Their names and formulas are important in understanding chemical reactions and compounds.
What is a polyatomic formula?
A polyatomic formula is a chemical formula that represents a polyatomic ion, which is a group of covalently bonded atoms that carries a net charge. These formulas are used to describe compounds that contain these complex ions, such as sulfate (SO4^2-) or ammonium (NH4+).
What is the polyatomic ions formula for carbonate?
The polyatomic ion formula for carbonate is CO3^2-.
What are 2 polyatomic ions that contain nitrogen?
The ammonium ion, NH4+, and the nitrate ion, NO3-.
When to use parenthesis when writing ionic compound formulas?
Parentheses are used in ionic compound formulas when multiple polyatomic ions are present. The parentheses are used to indicate a subscript that applies to all the elements inside the parentheses. For example, in the formula for calcium nitrate (Ca(NO3)2), the parentheses indicate that the nitrate ion (NO3) has a subscript of 2.

Is NaCO3 a polyatomic ion?
No, NaCO3 is not a polyatomic ion. NaCO3 is the formula for sodium carbonate, which is a compound composed of sodium ions (Na+) and carbonate ions (CO3 2-). The carbonate ion (CO3 2-) is a polyatomic ion.
What is the polyatomic ions formula for carbonate?
The polyatomic ion formula for carbonate is CO3^2-.
Are polyatomic ions positively charged?
Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.
What are 2 polyatomic ions that contain nitrogen?
The ammonium ion, NH4+, and the nitrate ion, NO3-.
What is the formula for magnesium hydrogen carbonate that contain polyatomic ions?
hydrogen carbonate (aka bicarbonate) is the polyatomic ion you're looking for. Mg(HCO3)2 Mg2+ (HCO3)-
Does MgSO4 contain polyatomic ions?
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.

For example, in the formula for calcium nitrate (Ca(NO3)2), the parentheses indicate that the nitrate ion (NO3) has a subscript of 2.
What polyatomic ions bond with other ions to form an ionic bond?
Polyatomic ions such as sulfate (SO4^2-), nitrate (NO3-), and phosphate (PO4^3-) can form ionic bonds with other ions to create compounds. These polyatomic ions have a charge that allows them to bond with ions of opposite charge through electrostatic attraction.
Do Polyatomic ions always contain oxygen?
In most of the cases it is true but SCN- , Transition metals complex ions and some organic poly atomic ions do not contain oxygen.
How should more than one polyatomic ion be indicated in a chemical formula?
One reason is that the composition of a polyatomic ion is fixed, just as that of a compound is fixed. If more than one polyatomic ion is present in an ionic compound, the use of parentheses allows a subscript to be used after the right parenthesis to designate the number of ions just as such subscript is used to designate the number of atoms in a compound.
