Ap Chemistry Worksheet 3 Naming Inorganic Compounds – Naming compounds is the most fundamental concept in chemistry. It involves assigning a distinctive name to one chemical substance based on its composition. When you name a compound will provide crucial information about its properties as well as its structure. There are several kinds of chemical substances, including the ionic compound, covalent compounds in addition to binary ones.
Naming Ionic Compounds
Ionic compounds are formed through electron transfer across the atom. They are made up from positively charged cations as well as negatively charged anions. The rules for naming Ionic compounds are as the following:
- Write the name and the cation first. Then, write what is the name for the anion.
- If the cation is charged with more than one possible charge mark the charge in Roman numbers in parentheses.
- If there is a possibility of polyatomic Ion, identify the Ion.
Examples:
- NaCl is known as sodium chloride.
- FeCl3 is known as iron(III) chloride.
- Mg(NO3)2 is also known as magnesium nitrate.
Naming Covalent Compounds
Covalent compounds are formed by the sharing of electrons among atoms. They are made up of molecules composed up of two or more atoms. The rules for naming covalent compounds are as according to:
- Note the name of first element in the formula.
- Write“the name” for the 2nd element in the formula, and change the end“-ide “-ide”.
- Use prefixes to identify the number of atoms for each element in the molecule. Except for“mono-” for the first element “mono-” for the first element.
Examples:
- Carbon dioxide is the name of CO2.
- N2O is named dinitrogen monoxide.
- This is known as sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are compounds made by two elements. The rules for names of binary compounds can be described as follows:
- Inscribe the name of the first element in the formula.
- Write the name of the second element in the formula, changing the end“ide “-ide”.
Examples:
- HCl is named hydrogen chloride.
- CO is a synonym for carbon monoxide.
- CaO is the term used to describe calcium oxide.
Practice Exercises
To further reinforce the learning, the worksheet will include examples of how to name ionic and covalent substances, in addition to binary compounds. The exercises will help students achieve a good understanding of how to name chemical compounds.
Ionic Compound Naming Exercises:
- Na2S
- KBr
- CaF2
- Al2O3
Covalent Compound Naming Exercises:
- CO
- SO2
- N2O4
- H2O2
Binary Compound Naming Exercises:

Through these exercises, students will be confident in naming chemical compounds and will be able apply the rules to other chemical compounds.
Conclusion:
Naming compounds is an essential concept in chemistry . It requires a good understanding of fundamental rules and principles to giving different compounds different names. When following the guidelines provided in this worksheet and experimenting using the provided exercises, students are able to confidently identify ionic and covalent in addition to binary, compounds. This information is crucial to achievement in chemistry. It will also provide the foundation for further research in the area.
