Naming Molecular Compounds Worksheet Answers Pogil

Naming Molecular Compounds Worksheet Answers Pogil – Naming chemical compounds is an essential concept in the field of chemistry. It involves assigning a unique name to each chemical compound according to its composition. What is the title of a compound contains important information about its properties and its structure. There are various types of chemical substances, including organic compounds, covalent ones in addition to binary ones.

Naming Ionic Compounds

Ionic compounds form through moving electrons around atoms. They are composed of positively charged cations and negatively charged anions. The rules for naming these compounds are as the following:

1. Inscribe the name of cation first, followed by an anion’s name.
2. If the cation could have multiple possible charges be sure to identify the charge using Roman numerals in parentheses.
3. If an anion’s structure is polyatomic ion identify the ion.

Examples:

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

Naming Covalent Compounds

Compounds that are covalent are formed through the exchange of electrons between atoms. They consist of molecules that are made consisting of two or more atoms. The guidelines for naming compounds that are covalent are as follows:

1. Note the name of first element of the formula.
2. Write the name of the second element in the formula, and change the end to “-ide”.
3. Use prefixes to indicate the amount of atoms that make up every element of the molecule. However, there is no need for“mono,” which is the name of the element “mono-” for the first element.

Examples:

• CO2 is a carbon dioxide derived name.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are compounds made from two elements. The rules for calling binary compounds are as in the following order:

1. Inscribe the name of the first element of the formula.
2. Write“Name” for second element of the formula, and change the end“-ide “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is named carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

For reinforcement of learning in the classroom, the worksheet contains drills for naming Ionic elements, covalent components, as well as binary compound. These exercises will help students acquire a deep understanding the rules to name chemical compounds.

Ionic Compound Naming Exercises:

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

Covalent Compound Naming Exercises:
