To write the chemical formula of a compound with polyatomic ions, first determine the charge of each ion. Then, balance the charges by crisscrossing the numerical values of the charges to determine the subscripts of each ion in the formula. Finally, write the formula with the proper subscripts for each ion to balance the charges.
What else can I help you with?
How are formulas written for ionic compounds with polyatomic compounds given their names?
You use the criss cross method to swith the charge of the element with the charge of the whole ion If the charge of the element is more than one then put the ion in parenthesis and then put the charge outside
A chemical formula is an expression used to represent?
the type and number of atoms that make up a molecule. It provides information on the elements present in the compound and the ratio in which they are combined. Chemical formulas are a way to communicate the composition of substances in a standardized manner.
What are formulas for compounds used instead of their common names?
Formulas are used because is a more short and simple system; all peoples understand a formula - a text may be undecipherable, the tranlation may be unsure, the common names have synonyms etc.
How do you write chemical formulas with oxidation numbers?
To write chemical formulas with oxidation numbers, first determine the oxidation number of each element in the compound based on their typical values. Then, use these oxidation numbers to balance the charges of cations and anions in the compound. Finally, write the chemical formula using subscripts to ensure that the overall charge of the compound is neutral.
How do you write the formulas for binary Ionic compounds?
To write the formulas of binary ionic compounds, you need to determine the charges of the ions involved. Then, you balance the charges to create a neutral compound. For example, in sodium chloride (NaCl), sodium has a +1 charge and chlorine has a -1 charge, so one of each ion is needed to balance the charges.

What are the Stock system names for the following compounds?
The Stock system is the current system to write chemical formulas; oxidation states are in parentheses, with Roman numerals.

What is the purpose of assigning a symbol to represent each element?
Assigning a symbol to represent each element allows for a more concise and universal way of referring to elements in the periodic table. It also simplifies chemical formulas and equations, making it easier to communicate and understand the composition of compounds.
Use oxidation numbers and their least common multiples to write what?
Formulas for compounds
What is a correct way to write a symbol?
IUPAC (International Union for Pure and Applied Chemistry) has rules for writing chemical symbols and formulas. They are valid in all languages.For compounds search in a library Nomenclature of inorganic compounds and Nomenclature of organic compounds, with the text adapted to your language, if necessary.See the links below.
When a chemical symbols and formulas are used as a shortcut to describe a chemical reaction is?
Chemical symbols and formulas are used in chemical reactions as a shortcut to represent the elements and compounds involved. They provide a concise way to convey the reactants, products, and stoichiometry of a reaction without having to write out the full names of the substances. This shorthand notation helps chemists communicate and understand reactions more efficiently.

How do you write the formula for the polyatomic ion in KOH.?
When KOH is placed in water, it ionizes to K+ and OH-, so the polyatomic ion is the OH- (hydroxyl anion).
