Writing Formulas And Naming Compounds Worksheet Answers Section 3

Writing Formulas And Naming Compounds Worksheet Answers Section 3 – Naming compounds is a key concept in the field of chemistry. It involves assigning an unique name to a chemical compound based on its composition. The name of a compound contains important information about its properties and structures. There are different types of chemical compounds, such as Ionic compounds, covalent substances in addition to binary ones.

Naming Ionic Compounds

Ionic compounds form through electron transfer from atoms. They are composed in positively charged caustics as well as negatively charged anions. The rules used to name ionic compounds are as they are:

1. Enter the name of the an atom first, followed by names of anion.
2. If the cation could have more than one possible charge make sure to indicate the charge with Roman numerals in parentheses.
3. If the anion is a polyatomic ion refer to the name of ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are formed by the exchange of electrons between atoms. They consist of molecules made comprised of two or three atoms. The guidelines for naming compounds that are covalent are as follows:

1. Inscribe the name of the first element in the formula.
2. Enter“the name” for the 2nd element of the formula, changing the ending“-ide. “-ide”.
3. Prefixes are used to indicate the number of atoms of each element in the molecule, with using the suffix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Compounds that are binary are those made up of two elements. The rules for the naming of binary compounds are as like:

1. Note the name of first element in the formula.
2. Write“double element” in the formula, and change the ending“-ide “-ide”.

Examples:

• It is known as hydrogen chloride.
• CO is the abbreviation for carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

To aid in learning and reinforce learning, the worksheet includes drills for naming Ionic compound, compounds with covalent bonds, as well as binary compound. The exercises will assist students to gain a thorough understanding of how 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

By finishing these exercises students will become more confident in formulating chemical names and be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is a crucial concept in chemistry . It requires a solid understanding of how to follow the guidelines and rules to giving different compounds different names. If you follow the rules laid out in this worksheet and experimenting with the included exercises students can comfortably identify covalent, ionic, as well as binary substances. This information is crucial to successful chemistry, and it will lay the foundation for further studies in the field.
