Naming Molecular Compounds Worksheet Chemistry If8766

Naming Molecular Compounds Worksheet Chemistry If8766 – Naming chemical compounds is an essential idea in the field of chemistry. It involves assigning an unique name to one chemical substance based on its composition. The name of a chemical compound will provide crucial information about the properties and structure of the compound. There are different kinds of chemical compounds, including chemical compounds that are ionic, covalent, along with binary and covalent compounds.

Naming Ionic Compounds

Ionic compounds are formed by the transfer of electrons between atoms. They are composed made up of positively charged anion and negatively charged anion. The rules to name ionic compounds are as follows:

1. Write the name of Cation first, then it’s anion’s name.
2. If the cation is charged with more than one charge mark the charge in Roman numerals in parentheses.
3. In the case of a multiatomic ion, refer to the name of anion.

Examples:

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

Naming Covalent Compounds

The formation of covalent compounds is caused 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 below:

1. Write the name for the first element of the formula.
2. Write your name for the element of the formula, changing the ending to “-ide”.
3. Prefixes can be used to indicate the number of atoms of every element of the molecule. This is not the case for“mono,” which is the name of the element “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• This is known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are made by two elements. The rules for the name of binary compounds are they are:

1. Inscribe the name of the first element of the formula.
2. Write“double element” in the formula, and change the ending“ide “-ide”.

Examples:

• HCl is named hydrogen chloride.
• CO is the scientific name for carbon monoxide.
• CaO is a name for calcium oxide.

Practice Exercises

To reinforce the learning The worksheet will provide examples of how to name ionic substances, chemical compounds that are covalent including binary ones. These exercises can help students acquire a deep understanding the rules for naming chemical compounds.

Ionic Compound Naming Exercises:

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