Writing And Naming Molecular Formulas For Binary Compounds Worksheet

Writing And Naming Molecular Formulas For Binary Compounds Worksheet – Naming compounds is a fundamental concept in chemical science. It involves assigning a distinctive name to each chemical compound according to its composition. It is important to know that the name given to a compound contains important information about its properties and structures. There are many kinds of chemical compounds, such as those with ionic properties, covalent compound, in addition to binary ones.

Naming Ionic Compounds

Ionic compounds can be formed by electron transfer across the atom. They are made up in positively charged caustics as well as negatively charged anions. The rules of naming ionic compounds are as these:

1. Write the name of compound first, and then that of the anion.
2. If the cation contains multiple possible charges be sure to identify the charge using Roman numerals within parentheses.
3. When the anion has a polyatomic ion you should use the name given to the ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are formed by sharing electrons among atoms. They are made up of molecules composed comprised of two or three atoms. The rules for naming covalent compounds are as like this:

1. Inscribe the name of the first element in the formula.
2. Enter your name for the element in the formula, and change the ending“-ide” to “-ide”.
3. Prefixes should be used to indicate amount of atoms that make up every element of the molecular structure, except for“mono,” for example “mono-” for the first element.

Examples:

• CO2 is a carbon dioxide derived name.
• N2O is named dinitrogen monoxide.
• It is also known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are substances made of two components. The rules for names for binary compounds are as in the following order:

1. Write the name and the first element of the formula.
2. Enter in the first element’s name of the formula, changing the ending“-ide” to “-ide”.

Examples:

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

Practice Exercises

To further reinforce the learning, the worksheet will include drills for naming Ionic and covalent substances, including binary ones. These activities will help students build 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:

By finishing these exercises students will develop confidence in making chemical compounds known and be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is an important aspect of chemistry that requires a thorough understanding of the rules and guidelines for creating names for different kinds and types of compounds. In following the principles laid out in this worksheet and practicing by using the included exercises, students are able to successfully identify ionic, chemical, or binary compound. This knowledge is vital to success in chemistry and lays the foundation for future studies in the area.
