How do you name compounds containing a polyatomic anion?
So when you see that you just write ammonium down step to name the anion.
How do you name covalent compounds with polyatomic ions?
The naming conventions of polyatomic ions must either be remembered or be referred to when writing the formula of the compound. The first step is to identify the elemental cation and anion, and then name them. The cation is named first, then the second part of the name is the anion and its known or deduced charge.
What are the five rules for naming ionic compounds?
Rules for naming simple ionic compounds.
- Name the metal by its elemental name.
- Name the nonmetal by its elemental name and an -ide ending.
- Name metals that can have different oxidation states using roman numerals to indicate positive charge. Example Fe2+ is Iron(II)
- Name polyatomic ions by their names.
What is the pattern for naming polyatomic ions?
In a similar fashion to the suffix pattern, the prefix pattern involved in naming polyatomic ions shows extreme values of oxygen atoms in the ions. The two important prefixes are “per” and “hypo.” If an ion has a “per” prefix, it means the ion has one more oxygen atom than does the ion with as “ate” suffix.

How do you write the formula for a compound containing a polyatomic ion?
To write the formula for a compound with a polyatomic ion, first write the symbol(or formula) for the cation followed by the symbol(or formula) for the anion. Then add subscripts as needed to balance the charges. a compound comprised of two elements; NaCi and Al2O3.

Well-known examples of such polyatomic ions are the sulfate ion (SO42–), the hydroxide ion (OH–), the hydronium ion (H3O+), and the ammonium ion (NH4+).
How do you name and write formulas for polyatomic ions?
What are the rules in naming compounds?
Rules for Naming Molecular Compounds
- Write the name for both elements.
- Change the ending of the second element to ide.
- Place prefixes in front of each element based on the number of atoms present.
- The prefix ‘mono’ is only used on the second non-metal in the chemical formula.
- There shouldn’t be two vowels in a row.
Why do I need to memorize polyatomic ions?
Polyatomic ions are important in chemistry because they are found in many common chemical compounds. Because of this, it is helpful to memorize the most common of these ions. Some teachers do allow students to use a list of polyatomic ions for exams while others do not.

What is the most common polyatomic ion?
However, this group of atoms is most stable when it has either lost of gained an electron and thus existed as a charged ion. These polyatomic ions are extremely common in chemistry and thus it is important to be able to both recognize and name them.

How do you name an ionic compound?
Summary
- Ionic compounds are named by stating the cation first, followed by the anion.
- Positive and negative charges must balance.
- Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses.
- Ternary compounds are composed of three or more elements.
How do you write the names of ionic compounds?
For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K+ and Cl- ions, is named potassium chloride.
What is the rule for naming compounds?
A molecular compound is usually composed of two or more nonmetal elements. Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.
How do you know when to use ITE or ate?
-ate and -ite are commonly used for polyatomic ions of Oxygen. -ate is used for the ion that has the largest number of Oxygen atoms. The -ite would be used for the ion with the smaller. NO2 and NO3 are known as Nitrite and Nitrate respectively.
What is the difference between ITE and ate suffix in polyatomic ions?
Naming Polyatomic Ions
The name of the ion usually ends in either -ite or -ate. The -ite ending indicates a low oxidation state. Thus,the NO2- ion is the nitrite ion. The -ate ending indicates a high oxidation state.
What compounds end in ate or ite?
