Naming Covalent Compounds Worksheet Chemfiesta Answers – Naming compounds is an important concept in chemistry. It involves assigning a distinctive name to the chemical compound on the basis of its composition. An individual’s name on a compound provides crucial information about its properties as well as its structure. There are various kinds of chemical substances, including chemical compounds that are ionic, covalent also known as binary compounds.
Naming Ionic Compounds
The Ionic compound is formed by the transfer of electrons between atoms. They are composed made up of positively charged anion as well as negatively charged anion. The rules of naming ionic compounds are as below:
- The name of the anion first, then the name of the anion.
- If the cation has more than one possible charge then indicate the charge using Roman numbers in parentheses.
- If the anion is a polyatomic ion identify the ion.
Examples:
- NaCl is named sodium chloride.
- FeCl3 is known as iron(III) chloride.
- Mg(NO3)2 is named magnesium nitrate.
Naming Covalent Compounds
Covalent compounds form through the exchange of electrons between atoms. They are composed of molecules made up of two or more atoms. The rules for naming covalent compounds are as follows:
- Note the name of first element in the formula.
- Enter in the first element’s name of the formula, and change the ending to “-ide”.
- Prefixes indicate the number of atoms present in each element in the molecule, except for“mono-” for the first element “mono-” for the first element.
Examples:
- CO2 is also known as carbon dioxide.
- N2O is named dinitrogen monoxide.
- This is known as sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are made by two elements. The rules for naming binary compounds are as below:
- Enter the name of the first element in the formula.
- Write“Name” for second element of the formula, and change the end“-ide “-ide”.
Examples:
- It is known as hydrogen chloride.
- CO is a synonym for carbon monoxide.
- The name CaO comes from calcium oxide.
Practice Exercises
To aid in learning and reinforce learning, the worksheet includes training exercises to help students name ionic molecules, covalent compound, as well as binary compound. These exercises will help students gain a thorough understanding of the rules that govern the naming of chemical compounds.
Ionic Compound Naming Exercises:
- Na2S
- KBr
