Naming Compounds Worksheets Pdf – Naming compounds is an important idea in chemical science. It involves the assignment of a unique name to an chemical compound, based on its composition. A name for a chemical compound gives important information about its properties as well as its structure. There are various types of chemical compound, including the ionic compound, covalent compounds also known as binary compounds.
Naming Ionic Compounds
Ionic compounds are formed through electron transfer between electrons. They consist of positively charged cations and negatively charged anion. The guidelines for naming ionic compounds are as according to:
- Note the name of the Cation first, then its name.
- If the cation contains multiple possible charges Indicate the charge with Roman numbers in parentheses.
- For anion that is not a polyatomic ion, take the name of that ion.
Examples:
- NaCl is known as sodium chloride.
- FeCl3 is also known as iron(III) chloride.
- Mg(NO3)2 is known under the name magnesium nitrate.
Naming Covalent Compounds
Covalent compounds are created through the exchange of electrons between atoms. They are composed of molecules made by two or more atoms. The guidelines for naming covalent compounds are as they are:
- Enter the name of the first element of the formula.
- Write“the name” for the 2nd element in the formula, and change the end“-ide. “-ide”.
- Prefixes can be used to indicate the quantity of atoms contained in each element in the molecule, with the prefix “mono-” for the first element.
Examples:
- CO2 is named carbon dioxide.
- N2O is named dinitrogen monoxide.
- SF6 is named sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are made of two components. The rules for the naming of binary compounds are as the following:
- Write the name of the first element of the formula.
- Enter“Name” for second element in the formula, changing the end“ide “-ide”.
Examples:
- The chemical name for HCl is hydrogen chloride.
- CO is the name given to carbon monoxide.
- CaO is the term used to describe calcium oxide.
Practice Exercises
To strengthen the understanding for students, the worksheets will include an exercise to practice naming ionic components, covalent compounds, in addition to binary compounds. These activities will help students achieve a good understanding of the rules that govern the naming of chemical compounds.
Ionic Compound Naming Exercises:
- Na2S
- KBr
- CaF2
- Al2O3
Covalent Compound Naming Exercises:
- CO
- SO2
- N2O4
- H2O2
Binary Compound Naming Exercises:
- Cl2O7
- P2S5
- BrF3
- NO
As they complete these exercises students will build confidence naming chemical compounds and will be able to apply the rules to other chemical compounds.
Conclusion:
Naming compounds is a crucial idea in chemistry that needs a solid understanding basic rules and procedures to naming different types of compounds. If you follow the rules laid out in this worksheet and experimenting with the included exercises, students are able to confidently name ionic, covalent, as well as binary substances. This skill is essential to success in chemistry and lays a strong foundation for further research in the field.
