Naming Compounds Worksheet Honors Chemistry – Naming compounds is an essential concept in the field of chemistry. It involves giving a unique name to any chemical compound based on its composition. A name for a chemical compound provides important information about its properties and structure. There are various kinds of chemical compounds. These include Ionic compounds, covalent substances as well as binary compound.
Naming Ionic Compounds
The Ionic compound is formed by moving electrons around atoms. They are composed with positively charged, cations as well as negatively charged anions. The rules for naming ionic compounds are as follows:
- Note the name of the cation first, followed by what is the name for the anion.
- If the cation contains more than one charge then indicate the charge using Roman numerals that are enclosed in parentheses.
- If there is a possibility of polyatomic ion identify the Ion.
Examples:
- NaCl is also known as sodium cyanide.
- FeCl3 is named iron(III) chloride.
- Mg(NO3)2 is known as magnesium nurate.
Naming Covalent Compounds
They are created by sharing electrons among atoms. They consist of molecules made by two or many atoms. The rules for naming covalent compounds are as according to:
- Name the first element of the formula.
- Enter an appropriate name for each element in the formula, changing the ending“-ide. “-ide”.
- Prefixes are used to indicate the number of atoms for every element of the molecular structure, except for“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.
Examples:
- Carbon dioxide is the name of CO2.
- N2O is named dinitrogen monoxide.
- So, SF6 is a sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are substances made from two elements. The rules for names for binary compounds are as in the following order:
- Inscribe the name of the first element of the formula.
- Write an appropriate name for each element in the formula, changing the end“-ide” to “-ide”.
Examples:
- The name of HCl is hydrogen cyanide.
- CO is known as carbon monoxide.
- Calcium oxide is also known as.
Practice Exercises
To aid in learning to reinforce the learning, the worksheet will contain activities for practicing naming ionic and covalent substances and binary compounds. The exercises will help students build a solid understanding of what rules are used for naming 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
If they can complete these assignments, students will become more confident in the naming of chemical compounds and be able apply the rules to other compounds.
Conclusion:
Naming compounds is an important aspect of chemistry that requires an understanding of how to follow the guidelines and rules for the naming of different kinds of compounds. When following the guidelines provided in this worksheet and practicing using the exercises included, students will be able be confident in naming ionic, covalent and binary compounds. This knowledge is vital to achievement in chemistry. It will also provide a strong foundation for further studies in the field.
