Naming Compounds And Writing Formulas Physical Science Worksheet

Naming Compounds And Writing Formulas Physical Science Worksheet – Naming compounds is an essential concept in the field of chemistry. It involves the assignment of a unique name to an chemical compound, based on its composition. It is important to know that the name given to a chemical compound provides important information about its properties as well as its structure. There are several kinds of chemical compounds. These include those with ionic properties, covalent compound in addition to binary ones.

Naming Ionic Compounds

Ionic compounds can be formed by electron transfer between electrons. They are made up comprise positively charged Cations and negatively charged anions. The rules for naming Ionic compounds are as in the following order:

1. Enter the name of the anion first, then it’s anion’s name.
2. If the cation has more than one possible charge identify the charge by using Roman numerals enclosed in parentheses.
3. The anion must be a polyatomic ion you should use the name given to the Ion.

Examples:

• NaCl is a common name for sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium Nitrate.

Naming Covalent Compounds

Covalent compounds are made by the sharing of electrons between atoms. They consist of molecules that are made consisting of two or even more atoms. The guidelines for naming compounds that are covalent are as follows:

1. Write the name for the first element of the formula.
2. Enter“ide” in place of “ide” in the formula, and change the end“-ide. “-ide”.
3. Use prefixes for the number of atoms present in every element of the molecule. The exception is“mono” as a prefix “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• N2O is named dinitrogen monoxide.
• So, SF6 is a sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are composed from two elements. The rules for names for binary compounds are as in the following order:

1. Write the name of the first element of the formula.
2. Enter an appropriate name for each element of the formula, changing the end in the form of “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is a synonym for carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

To enhance the learning experience this worksheet will offer activities for practicing naming ionic molecules, covalent compound, as well as binary compound. The exercises 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:
