Review Naming Chemical Compounds Worksheet Key – Naming chemical compounds is an essential concept in the field of chemistry. It involves assigning an unique name to the chemical compound on the basis of its composition. An individual’s name on a compound is a crucial indicator of the properties and structure of the compound. There are several kinds of chemical compounds. This includes organic compounds, covalent ones, as well as binary compound.
Naming Ionic Compounds
Ionic compounds are formed through the transfer of electrons between atoms. They consist of positively charged cations and negatively charged anion. The rules for naming ionic compounds are as the following:
- Write the name and the cation first, followed by an anion’s name.
- If the cation is charged with multiple possible charges, indicate the charge using Roman numbers enclosed in parentheses.
- In the case of a multiatomic ion, choose the name of the anion.
Examples:
- NaCl is named sodium chloride.
- FeCl3 is also known as iron(III) chloride.
- Mg(NO3)2 is named magnesium nitrate.
Naming Covalent Compounds
The formation of covalent compounds is caused by the exchange of electrons between atoms. They consist of molecules that are made consisting of two or more atoms. The rules for naming covalent compounds are as like this:
- Inscribe the name and the first element of the formula.
- Enter“name” of second component in the formula, and change the ending“-ide “-ide”.
- Use prefixes to identify the number of atoms of every element of the molecular structure, except for using the suffix “mono-” for the first element.
Examples:
- CO2 is named carbon dioxide.
- N2O is named dinitrogen monoxide.
- The term SF6 stands for sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are made up of two elements. The rules for using the term binary compound are as these:
- Write the name for the first element of the formula.
- Enter“double element” of the formula, and change the end“-ide. “-ide”.
Examples:
- Hydrogen chloride is the name given to it.
- CO is a synonym for carbon monoxide.
- CaO is also known as calcium oxide.
Practice Exercises
To reinforce the learning to reinforce the learning, the worksheet will contain training exercises to help students name ionic substances, chemical compounds that are covalent and binary compounds. These exercises will aid students establish a firm understanding of the rules used to name chemical compounds.
Ionic Compound Naming Exercises:
