Formulas Naming Compounds Worksheet Answers

Formulas Naming Compounds Worksheet Answers – Naming compounds is a key concept in chemistry. It involves granting a unique name to compounds based upon its composition. When you name a compound is a crucial indicator of its properties and the structure. There are various types of chemical compounds, including those with ionic properties, covalent compound, or binary substances.

Naming Ionic Compounds

Ionic compounds are formed through electron transfer from atoms. They consist from positively charged cations as well as negatively charged anions. The guidelines for naming ionic compounds are as according to:

1. Note the name of the cation first, followed by that of the anion.
2. If the cation may have more than one possible charge then indicate the charge using Roman numbers in parentheses.
3. For anion that is not a polyatomic Ion, make use of the name for the ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds form through sharing electrons among atoms. They consist of molecules that are made from two or more atoms. The rules for naming covalent compounds are as they are:

1. Then write the name of first element in the formula.
2. Enter an appropriate name for each element in the formula, and change the ending“ide “-ide”.
3. Prefixes can be used to indicate the amount of atoms found in each element in the molecular structure, except for“mono,” for example “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Binary compounds are the ones made from two elements. The rules for names of binary compounds can be described as like:

1. Then write the name of first element in the formula.
2. Write the name of the second element of the formula, and change the ending“-ide. “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is the abbreviation for carbon monoxide.
• CaO is named calcium oxide.

Practice Exercises

To enhance the learning experience for students, the worksheets will include drills for naming Ionic compounds, covalent compounds including binary ones. These exercises will help students get a better understanding of what rules are used for naming chemical compounds.

Ionic Compound Naming Exercises:

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

Covalent Compound Naming Exercises:

1. CO
2. SO2
3. N2O4
4. H2O2

Binary Compound Naming Exercises:

1. Cl2O7
2. P2S5
3. BrF3
4. NO

In completing these tests, students will develop confidence in the naming of chemical compounds and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential idea in chemistry that requires a deep understanding of the rules and guidelines for Naming different kinds of compounds. Through following the steps laid out in this worksheet, and working through the exercises provided, students will be able to comfortably identify covalent, ionic, and binary compounds. This knowledge is vital to success in chemistry . It also provides an excellent foundation for future studies in the area.
