Naming Compounds And Writing Formulas Worksheet Answer Key

Naming Compounds And Writing Formulas Worksheet Answer Key – Naming compounds is the most fundamental idea in the field of chemistry. It is about assigning a specific name to an chemical compound, based on its composition. Names of compound provides crucial information about its properties and structure. There are various types that chemical compounds can be found, including organic compounds, covalent ones, in addition to binary ones.

Naming Ionic Compounds

The Ionic compound is formed by an exchange of electrons among atoms. They consist of positively charged cations as well as negatively charged anion. The rules of naming ionic compounds are as they are:

1. Write the name of cation first, followed by it’s anion’s name.
2. If the cation may have more than one possible charge Indicate the charge with Roman numerals that are enclosed in parentheses.
3. In the case of a multiatomic Ion, identify the ion.

Examples:

• NaCl is also known as sodium chloride.
• FeCl3 is also known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium Nitrate.

Naming Covalent Compounds

Covalent compounds are formed by sharing electrons among atoms. They are made up of molecules composed consisting of two or more atoms. The rules for naming compounds that are covalent are as in the following order:

1. Inscribe the name and the first element of the formula.
2. Enter in the first element’s name of the formula, changing the end“ide “-ide”.
3. Use prefixes for 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 named carbon dioxide.
• N2O is named dinitrogen monoxide.
• This is known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist up of two elements. The rules for names of binary compounds can be described as below:

1. Name the first element in the formula.
2. Enter an appropriate name for each element of the formula, and change the end in the form of “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is a chemical compound known as carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

To aid in learning The worksheet will provide the practice of naming ionic chemicals, compound covalent, along with binary and covalent compounds. The exercises will help students gain a thorough understanding of how to name chemical compounds.

Ionic Compound Naming Exercises:

1. Na2S
2. KBr
3. CaF2
4. Al2O3

Covalent Compound Naming Exercises:
