Naming Binary Molecular Compounds Worksheet 3 Answers

Naming Binary Molecular Compounds Worksheet 3 Answers – Naming compounds is the most fundamental idea in chemistry. It is the process of assigning a distinct name to a chemical compound based on its composition. A name for a compound is a crucial indicator of its properties and structure. There are several kinds of chemical compounds, including those with ionic properties, covalent compound also known as binary compounds.

Naming Ionic Compounds

Ionic compounds are created by electron transfer between electrons. They are composed from positively charged cations as well as negatively charged anions. The rules of naming ionic compounds are as like this:

1. Write the name of initial cation, followed by your name and the name of the anion.
2. If the cation has more than one charge mark the charge in Roman numerals within parentheses.
3. In the case of a multiatomic Ion, take the name of that anion.

Examples:

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

Naming Covalent Compounds

Compounds that are covalent are formed through the sharing of electrons among atoms. They consist of molecules made comprising two or more atoms. The guidelines for naming covalent compounds are as below:

1. Then write the name of first element in the formula.
2. Write an appropriate name for each element of the formula, changing the end to “-ide”.
3. Prefixes should be used to indicate number of atoms in each element in the molecule, except for“mono,” for example “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

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

1. Inscribe the name of the first element of the formula.
2. Enter“double element” of the formula, and change the ending“-ide “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is the abbreviation for carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

To help reinforce learning it will be accompanied by training exercises to help students name ionic chemicals, compound covalent and binary compounds. The exercises will assist students to get a better understanding of the rules that govern the naming of 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

When they complete these activities, learners will become confident in formulating chemical names and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential idea in chemistry that requires a deep understanding of how to follow the guidelines and rules to giving different compounds different names. When following the guidelines provided in this worksheet and practicing with the included exercises students will be able to be confident in naming ionic, covalent, or binary compound. This information is crucial to success in chemistry and lays an excellent foundation for future research in the field.
