Naming Ions And Chemical Compounds Worksheet 1 – Naming compounds is an essential concept in the field of chemistry. It involves giving a unique name to compounds based upon its composition. The name of a chemical compound offers important information on its properties and its structure. There are various kinds of chemical compound, including chemical compounds that are ionic, covalent or binary substances.
Naming Ionic Compounds
Ionic compounds can be formed by electron transfer across the atom. They are composed comprise positively charged Cations as well as negatively charged anion. The rules used to name ionic compounds are as below:
- Note the name of the an atom first, followed by your name and the name of the anion.
- If the cation may have multiple possible charges identify the charge by using Roman numerals enclosed in parentheses.
- If it is a polyatomic ion use the name of the anion.
Examples:
- NaCl is named 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 form through the exchange of electrons between atoms. They consist of molecules made by two or many atoms. The guidelines for naming covalent compounds are as in the following order:
- Inscribe the name of the first element in the formula.
- Enter“Element 2” as the title in the formula, changing the end to “-ide”.
- Prefixes indicate the number of atoms present in each element in the molecule. The exception is“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.
Examples:
- CO2 is also known as carbon dioxide.
- N2O is named dinitrogen monoxide.
- The name SF6 refers to sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are those made by two elements. The rules for choosing the proper name for binary compounds is as like:
- Write the name of the first element of the formula.
- Enter“double element” in the formula, and change the end to “-ide”.
Examples:
- The name of HCl is hydrogen cyanide.
- CO is the abbreviation for carbon monoxide.
- The name CaO comes from calcium oxide.
Practice Exercises
In order to reinforce the learning process this worksheet will offer training exercises to help students name ionic molecules, covalent compound, also known as binary compounds. The exercises will assist students to establish a firm understanding of the rules used to name 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 develop confidence in the identification of chemical compounds, and will be able to apply the rules to other chemical compounds.
Conclusion:
Naming compounds is an essential concept in chemistry . It requires a clear understanding of principles and regulations to naming different types of compounds. By following the rules outlined in this worksheet, and working with the included exercises, students will be able confidently name ionic, covalent, also binary compounds. This knowledge is vital to the success of chemistry and provides the foundation for future studies in the field.
