Naming Compounds Review Worksheet – Naming compounds is a key concept in the field of chemistry. It involves assigning an unique name to chemicals based on its composition. Names of chemical compound can provide important information regarding the properties and structure of the compound. There are various kinds of chemical compounds. This includes chemical compounds that are ionic, covalent, and even binary compounds.
Naming Ionic Compounds
Ionic compounds are formed through an exchange of electrons among atoms. They are made up of positively charged cations as well as negatively charged anion. The rules for naming Ionic compounds are as follows:
- Write the name for the anion first, then names of anion.
- If the cation is charged with more than one possible charge identify the charge by using Roman numbers enclosed in parentheses.
- If there is a possibility of polyatomic ion, you should use the name given to the Ion.
Examples:
- NaCl is also known as sodium chloride.
- FeCl3 is known as iron(III) chloride.
- Mg(NO3)2 is also known as magnesium nitrate.
Naming Covalent Compounds
Covalent compounds are created through sharing electrons among atoms. They are made up of molecules composed consisting of two or even more atoms. The guidelines for naming compounds that are covalent are as they are:
- Enter the name of the first element in the formula.
- Enter the name of the second element of the formula, changing the ending to “-ide”.
- Prefixes can be used to indicate the quantity of atoms contained in each element in the molecule. There is no prefix for“mono,” for example “mono-” for the first element.
Examples:
- Carbon dioxide is the name of CO2.
- N2O is named dinitrogen monoxide.
- The term SF6 stands for sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are substances made up of two elements. The rules for the naming of binary compounds are as follows:
- Then write the name of first element in the formula.
- Write an appropriate name for each element of the formula, and change the ending“-ide. “-ide”.
Examples:
- The chemical name for HCl is hydrogen chloride.
- CO is a synonym for carbon monoxide.
- CaO is also known as calcium oxide.
