Writing Formulas And Naming Binary Compounds Worksheet

Writing Formulas And Naming Binary Compounds Worksheet – Naming compounds is an important idea in chemistry. It involves the assignment of a unique name to the chemical compound on the basis of its composition. What is the title of a compound provides important information about its properties as well as its structure. There are many kinds of chemical compounds, such as covalent compounds, ionic compounds, and even binary compounds.

Naming Ionic Compounds

Ionic compounds arise from electron transfer from atoms. They are made up made up of positively charged anion as well as negatively charged anions. The rules of naming ionic compounds are as in the following order:

1. Enter the name of the initial cation, followed by your name and the name of the anion.
2. If the cation contains multiple possible charges be sure to identify the charge using Roman numerals in brackets.
3. If an anion’s structure is polyatomic ion take the name of that Ion.

Examples:

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

Naming Covalent Compounds

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

1. Write the name for 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 amount of atoms found in each element in the molecule. There is no prefix for“mono-,” the particular prefix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

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

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

Examples:

• The chemical name for HCl is hydrogen chloride.
• CO is the name given to carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

To further reinforce the learning for students, the worksheets will include practices for naming ionic components, covalent compounds along with binary and covalent compounds. The exercises will assist students to 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 have confidence being able to identify chemical compounds and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an important concept in chemistry , and requires a thorough understanding of these rules as well as guidelines to making names for various kinds of compounds. By adhering to the guidelines set forth in this worksheet, and working using the exercises included, students will be able to be confident in naming ionic, covalent, and binary compounds. This is vital for the success of chemistry and provides a strong foundation for further research in the field.
