Naming Polyatomic Compounds Practice Worksheet

Naming Polyatomic Compounds Practice Worksheet – Naming compounds is a key concept in chemical science. It involves the assignment of a unique name to any chemical compound based on its composition. The name of a chemical compound can provide important information regarding its properties and structures. There are various kinds that chemical compounds can be found, including chemical compounds that are ionic, covalent as well as binary compound.

Naming Ionic Compounds

Ionic compounds are produced by transfers of electrons across atoms. They are made up mostly of positively charged electrons and negatively charged anion. The guidelines for naming ionic compounds are as according to:

1. Inscribe the name of cation first. Then, write that of the anion.
2. If the cation is charged with more than one charge Indicate the charge using Roman numerals that are enclosed in parentheses.
3. If there is a possibility of polyatomic ion, make use of the name for the ion.

Examples:

• NaCl is a synonym for sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium nitrate.

Naming Covalent Compounds

Covalent compounds are made by the exchange of electrons between atoms. They consist of molecules made comprising two or more atoms. The rules for naming compounds that are covalent are as below:

1. Write the name of the first element in the formula.
2. Enter your name for the element of the formula, and change the ending“-ide. “-ide”.
3. Prefixes indicate the number of elements in every element of 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.
• So, SF6 is a sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are compounds made by two elements. The rules for calling binary compounds are as follows:

1. Enter the name of the first element of the formula.
2. Write the name of the second element in the formula, and change the end“-ide” to “-ide”.

Examples:

• The chemical name for HCl is hydrogen chloride.
• CO is a chemical compound known as carbon monoxide.
• CaO is a name for calcium oxide.
