Naming Covalent Compounds Type 3 Worksheet Answer Key – Naming of compounds is a fundamental idea in chemistry. It involves granting a unique name to each chemical compound according to its composition. It is important to know that the name given to a chemical compound is a crucial indicator of the properties and structure of the compound. There are many types of chemical compounds. These include those with ionic properties, covalent compound, the binary type of compounds.
Naming Ionic Compounds
Ionic compounds are formed through the transfer of electrons between atoms. They are composed in positively charged caustics and negatively charged anions. The rules to name ionic compounds are as below:
- Enter the name of the catalytic cation in the first place, then names of anion.
- If the cation may have multiple possible charges then indicate the charge using Roman numerals within parentheses.
- When the anion has a polyatomic ion select the name of the anion.
Examples:
- NaCl is also known as sodium chloride.
- FeCl3 is known as iron(III) chloride.
- Mg(NO3)2 is known as magnesium nitrate.
Naming Covalent Compounds
Covalent compounds arise from sharing electrons among atoms. They are made up of molecules composed comprising two or more atoms. The rules for naming covalent compounds are as these:
- Name the first element in the formula.
- Enter“Element 2” as the title of the formula, changing the ending“-ide” to “-ide”.
- Utilize prefixes to represent the amount of atoms found in each element in the molecule. However, there is no need for“mono” as a prefix “mono-” for the first element.
Examples:
- CO2 is named carbon dioxide.
- N2O is named dinitrogen monoxide.
- SHF is also known as sulfur Hexafluoride.
Naming Binary Compounds
Binary compounds consist of two components. The rules for the name of binary compounds are the following:
- Enter the name of the first element of the formula.
- Write“double element” in the formula, and change the end in the form of “-ide”.
Examples:
- Hydrogen chloride is also known as hydrogen.
- CO is a synonym for carbon monoxide.
- CaO is named calcium oxide.
Practice Exercises
