Www Chemfiesta Com Naming Chemical Compounds Worksheet – Naming compounds is an essential concept in chemical science. It is the process of assigning a distinct name to a chemical compound based on its composition. A name for a chemical compound contains important information about its properties and the structure. There are several kinds of chemical compounds. These include organic compounds, covalent ones, as well as binary compound.

Naming Ionic Compounds

Ionic compounds are created by transfers of electrons across atoms. They are composed with positively charged, cations as well as negatively charged anions. The rules for naming these compounds are as the following:

1. Write the name of the an atom first, followed by it’s anion’s name.
2. If the cation contains more than one possible charge, indicate the charge using Roman numerals in brackets.
3. If the anion is a polyatomic ion refer to the name of anion.

Examples:

• NaCl is known as 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 the sharing of electrons among atoms. They are composed of molecules made by two or more atoms. The guidelines for naming compounds that are covalent are as they are:

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 to “-ide”.
3. Use prefixes for the number of atoms for each element in the molecule, with“mono-,” the particular prefix “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

Binary compounds are the ones made by two elements. The rules for calling binary compounds are as the following:

1. Write the name and the first element of the formula.
2. Write the name of the second element of the formula, changing the ending“-ide” to “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is a chemical compound known as carbon monoxide.
• CaO is named calcium oxide.

Practice Exercises

To help reinforce learning it will be accompanied by an exercise to practice naming ionic elements, covalent components or binary substances. This will help students build a solid understanding of the rules used 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 students will build confidence making chemical compounds known and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is an important idea in chemistry that requires a solid understanding of what rules apply and the best practices for giving different compounds different names. Following the guidelines outlined in this worksheet and practicing with the included exercises students will be able to comfortably identify covalent, ionic, in addition to binary, compounds. This knowledge is essential for the success of chemistry and provides the foundation for future research in the field.
