Grade 10 Science Naming Compounds Worksheet

Grade 10 Science Naming Compounds Worksheet – Naming compounds is the most fundamental concept in the field of chemistry. It involves giving a unique name to compounds based upon its composition. In addition, the name assigned to the compound provides crucial information about its properties and structure. There are different types of chemical compounds, including covalent compounds, ionic compounds or binary substances.

Naming Ionic Compounds

Ionic compounds are formed through electron transfer amongst atoms. They are composed of positively charged cations as well as negatively charged anion. The rules for naming Ionic compounds are as these:

1. Write the name for the Cation first, then its name.
2. If the cation is charged with more than one possible charge Indicate the charge with Roman numbers in parentheses.
3. In the case of a multiatomic Ion, use the name of the anion.

Examples:

• NaCl is the name given to sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is named magnesium nitrate.

Naming Covalent Compounds

Covalent compounds are made by the sharing of electrons between atoms. They are composed of molecules made from two or more atoms. The guidelines for naming compounds that are covalent are as the following:

1. Enter the name of the first element in the formula.
2. Write“name” of second component of the formula, changing the ending“-ide “-ide”.
3. Prefixes should be used to indicate amount of atoms that make up each element in the molecule. There is no prefix for“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• So, SF6 is a sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are those made from two elements. The rules for naming binary compounds are as these:

1. Write the name of the first element in the formula.
2. Enter“name” of second component in the formula, changing the end“-ide. “-ide”.

Examples:

• It is known as hydrogen chloride.
• CO is the abbreviation for carbon monoxide.
• Calcium oxide is known as CaO.

Practice Exercises

In order to reinforce the learning process and reinforce learning, the worksheet includes drills for naming Ionic compounds, covalent compounds and binary compounds. These exercises can help students establish a firm 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 become more confident in making chemical compounds known and be able apply the rules to other compounds.

Conclusion:

Naming compounds is a crucial concept in chemistry . It requires an understanding of specific rules to naming different types of compounds. Through following the steps laid out in this worksheet and practicing with the included activities, students will be able to be confident in naming ionic, covalent, in addition to binary, compounds. This is a must for succeeding in chemistry and creates the foundation for future research in the area.
