Writing Formulas And Naming Compounds Worksheet South Pasadena

Writing Formulas And Naming Compounds Worksheet South Pasadena – Naming of compounds is a fundamental idea in chemical science. It involves giving a unique name to compounds based upon its composition. An individual’s name on a chemical compound is a crucial indicator of its properties and the structure. There are different types of chemical compounds, such as Ionic compounds, covalent substances and binary compounds.

Naming Ionic Compounds

Ionic compounds are formed by transfers of electrons across atoms. They consist with positively charged, cations and negatively charged anion. The rules of naming ionic compounds are as these:

1. Note the name of the initial cation, followed by names of anion.
2. If the cation may have more than one possible charge then indicate the charge using Roman numerals inside parentheses.
3. If the anion is a polyatomic ion use the name of the ion.

Examples:

• NaCl is a synonym for sodium chloride.
• FeCl3 is named iron(III) chloride.
• Mg(NO3)2 is known as magnesium nitrate.

Naming Covalent Compounds

Compounds that are covalent are formed through the sharing of electrons between atoms. They consist of molecules that are made comprised of two or three atoms. The guidelines for naming compounds that are covalent are as the following:

1. Note the name of first element of the formula.
2. Write“name” of second component in the formula, and change the ending“-ide “-ide”.
3. Prefixes indicate the number of atoms for each element in the molecule, except for“mono-” which indicates the number of atoms in the molecule “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 compounds made of two components. The rules for using the term binary compound are as they are:

1. Then write the name of first element of the formula.
2. Write“name” of second component of the formula, and change the ending“-ide” to “-ide”.

Examples:

• It is known as hydrogen chloride.
• CO is the name given to carbon monoxide.
• CaO is the term used to describe calcium oxide.

Practice Exercises

To help reinforce learning it will be accompanied by an exercise to practice naming ionic elements, covalent components, along with binary and covalent compounds. The exercises will assist students to establish a firm 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

Through these exercises, students will have confidence formulating chemical names and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is an important concept in chemistry that needs a solid understanding what rules apply and the best practices to the naming of different kinds of compounds. In following the principles laid out in this worksheet and experimenting by using the included exercises, students will be able to be confident in naming ionic, covalent, and binary compounds. This knowledge is essential for the success of chemistry and provides an excellent foundation for future research in the area.
