Naming Compounds Worksheet Key

Naming Compounds Worksheet Key – Naming compounds is a fundamental idea in chemistry. It involves giving a unique name to an chemical compound, based on its composition. Names of compound can provide important information regarding its properties and structure. There are different kinds of chemical compounds, such as Ionic compounds, covalent substances, the binary type of compounds.

Naming Ionic Compounds

Ionic compounds are formed by the transfer of electrons between atoms. They are made up mostly of positively charged electrons and negatively charged anion. The rules for naming Ionic compounds are as these:

1. Enter the name of the cation first. Then, write an anion’s name.
2. If the cation could have multiple possible charges identify the charge by using Roman numbers in parentheses.
3. When the anion has a polyatomic Ion, make use of the name for the Ion.

Examples:

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

Naming Covalent Compounds

Compounds that are covalent are formed through sharing electrons among atoms. They are made up of molecules composed from two or more atoms. The guidelines for naming compounds that are covalent are as like this:

1. Write the name for the first element in the formula.
2. Write“name” of second component in the formula, changing the ending“-ide” to “-ide”.
3. Prefixes can be used to indicate the quantity of atoms contained in every element of the molecule. Except for“mono” as a prefix “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• SHF6 is the name given to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are composed up of two elements. The rules for the naming of binary compounds are as like:

1. Enter the name of the first element of the formula.
2. Enter“I” as the title of your second ingredient in the formula, changing the ending to “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is known as carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

In order to reinforce the learning process this worksheet will offer an exercise to practice naming ionic components, covalent compounds, as well as binary compound. These exercises will aid students develop a solid understanding of the rules to name 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

As they complete these exercises learners will become confident in the identification of chemical compounds, and will be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential concept in chemistry that demands a firm understanding basic rules and procedures to creating names for different kinds and types of compounds. Through following the steps laid out in this worksheet and practicing with the included exercises students will be able to easily identify ionic, covalent in addition to binary, compounds. This knowledge is vital to succeeding in chemistry and creates a strong foundation for further studies in the area.
