Section 6.3 Naming Compounds And Writing Formulas Worksheet With Answers

Section 6.3 Naming Compounds And Writing Formulas Worksheet With Answers – Naming compounds is a key idea in chemistry. It is about assigning a specific name to the chemical compound on the basis of its composition. An individual’s name on a compound provides important information about the properties and structure of the compound. There are many kinds of chemical compounds, such as covalent compounds, ionic compounds, along with binary and covalent compounds.

Naming Ionic Compounds

Ionic compounds are produced by the transfer of electrons between atoms. They consist with positively charged, cations and negatively charged anion. The rules for naming ionic compounds are as in the following order:

1. Enter the name of the Cation first, then its name.
2. If the cation could have multiple possible charges mark the charge in Roman numbers enclosed in parentheses.
3. If an anion’s structure is polyatomic ion choose 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

The formation of covalent compounds is caused by the sharing of electrons among atoms. They are composed of molecules made comprised of two or three atoms. The rules for naming compounds that are covalent are as in the following order:

1. Inscribe the name of the first element in the formula.
2. Write an appropriate name for each element in the formula, and change the end to “-ide”.
3. Prefixes indicate the quantity of atoms contained in every element of the molecule, except for“mono-,” the particular prefix “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are made up of two elements. The rules for calling binary compounds are as below:

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

Examples:

• It is known as hydrogen chloride.
• CO is a synonym for carbon monoxide.
• Calcium oxide is known as CaO.
