What ionic compounds have polyatomic ions?

Indeed, most ionic compounds contain polyatomic ions. Well-known examples are sodium hydroxide (NaOH) with OH^- as the polyatomic anion, calcium carbonate (CaCO₃), and ammonium nitrate (NH₄NO₃), which contains two polyatomic ions: NH⁺ and NO₃^-.

How do you know if a compound contains a polyatomic ion?

The cation is written first in the name; the anion is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.

What is the polyatomic ion in caco3?

Calcium carbonate is made up of polyatomic carbonate anions, CO32- and monatomic calcium cations, Ca2+.

How do ionic compounds contain polyatomic ions?

Rule 1. The cation is written first in the name; the anion is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.

How are polyatomic ions named when found in ionic compounds?

An ionic compound is named first by its cation and then by its anion. ... If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. The polyatomic ion name stays the same.

Can molecular compounds contain polyatomic ion?

Polyatomic ions are ions. However, the atoms in polyatomic ions are held together by covalent bonds. Compounds containing polyatomic ions are ionic compounds. ... A molecular compound is a molecule formed between two non-metals from right of the metalloid staircase.

Is Na+ a polyatomic ion?

For example, NaNO2 is named according to its cation, Na+ (sodium), and its polyatomic anion, ... both polyatomic ions. • For example, NH4NO3 is ammonium nitrate.

Is KNO3 a polyatomic ion?

For example, we name KNO3 using its cation, K+, potassium, and its polyatomic anion, NO3-, nitrate.

Is NaF a polyatomic ion?

For example, NaF is also known as sodium fluoride. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. The polyatomic ion name stays the same. For example, Ca(NO₃)₂ is called calcium nitrate.

Are polyatomic ions cations or anions?

Note that the vast majority of the ions listed are anions—there are very few polyatomic cations. The vast majority of polyatomic ions are anions, many of which end in -ate or -ite. Notice that in some cases, such as nitrate (NO−3) and nitrite (NO−2), there are multiple anions that consist of the same two elements.

Are all polyatomic ions nonmetals?

Groups of covalently bonded semimetals or nonmetals which are charged are called polyatomic ions. Common examples include sulfate dianion, nitrate anion, phosphate trianion, etc. These polyatomic ions are commonly paired with metals forming ionic compounds.

Is NH4 a polyatomic ion?

NH4 is the positive polyatomic Ammonium. It is one of the few positive polyatomic ions.
